CFD Simulation and Analysis Project

CFD - Computational Fluid Dynamics - CFD Simulation and Analysis Project

In continuum mechanics, fluid mechanics to form one large branch. Fluid mechanics begins with the same principles of solid mechanics, but what distinguishes them from one another, is a fluid unlike solids are not able to withstand shear stress. Knowing this, it is planned equations for fluid motion analysis. These equations to respect both the British and the French mathematician called Navier-Stokes equations. CFD - Computational Fluid Dynamics solve the Navier-Stokes equation for the small size of the original model. In this way, the total desired volume is divided into very small volumes in operation meshing and after applying the boundary conditions, the equation is solved for all elements.

Computational Fluid Dynamics- CFD- in terms of the overall trend is similar to static and dynamic FEM analysis. Both methods are used to solve a much smaller element than the original model.

Today, with increasing computer processing speeds, CFD and FEM analyzes have found a special place in the design and failure analysis. Important things that can be calculated in Computational Fluid Dynamics:

Plot speed, temperature, and fluid pressure at any point of the model

Plots and counter the speed, temperature, and fluid pressure in the interior and exterior surfaces

Diagram of the fluid flow path

heat transfer charts and plots in the outer surfaces and boundary

Calculation of speed, temperature, and pressure at different levels and volumes

Diagram of the flow path

CFD and thermal simulation inside an shell and tube heat exchanger

Analysis and simulation of heat transfer and fluid that can be done with software such as Fluent, Ansys, and Flow works used in different parts of the industry, some of these include:

- Analysis and simulation of industrial ventilation and air conditioning - HVAC CFD

- Analysis and simulation of turbine and compressor

Industrial consulting, product optimization

Industrial consulting and product optimization

How can we optimize a product?
What are the processes and methods of prototyping and endemic manufacturing of products or machines?
How can we define the relationship between R&D, manufacturing, and QC teams?
Is there any way to make prototyping more productive?
Which one should we focus on? Time, cost, or quality?
What can we do to reduce the manufacturing cost and where, to begin with?
What are the differences between product design, reverse engineering, and a copy?
These and many other questions need to be asked before a manager decides to enter a new market. Without a doubt, management has differences, as well as similarities in distinct branches and these differences, make demand for professional knowledge in any field of business for a manager.

Defining the market and product, bench marketing, study the weaknesses and strengths, reverse engineering and re-design, patent-pending, prototyping and mass producing, marketing, system control and systematic innovating are all strategic necessities of a business that needs planning.

One of the key points of this section is developing a new product, and to achieve this goal there are usually two procedures: reverse engineering or product design.
Reverse engineering is the procedure of obtaining technical knowledge by studying its similar products. Unfortunately many mistake the phrase “Studying” with “measuring” and they only check dimensions, materials, surface hardness, and other physical properties. But reverse engineering means understanding the reason behind every choice in process of engineering design.
This is the only way that a company achieves technical knowledge and will be able to develop a product by itself. Another reason behind this “studying” is to endemic a product. For example, the main product may use imperial units, but your country uses metric units. The size of standard parts like bolts, bearings, profiles, etc. are different and therefore you need some analysis before replacing them.
ARA Co with its extensive experience in reverse engineering and design of new products is now ready to share its knowledge with industries and investors in the following sectors:

• Marketing and sale engineering
• Business development/start-up from prototyping to mass production
• Reverse engineering and product design consulting
• Industrial design, engineering design, and product design
• Power calculation and selection of power supply chains such as electric motor and gearbox

Free surface fluid and flow simulation

Free-surface modeling

In physics, a free surface flow is the surface of a fluid flowing that is subjected to both zero perpendicular normal stress and parallel shear stress. This can be the boundary between two homogeneous fluids, like water in an open container and the air in the Earth's atmosphere that form a boundary at the open face of the container. Computation of free surfaces is complex because of the continuous change in the location of the boundary layer. Conventional methods of computation are insufficient for such analysis. Therefore, special methods are developed for the computation of free surface flows. Source : https://en.wikipedia.org/wiki/Computational_methods_for_free_surface_flow

We can handle free_surface flow modeling and simulation with best quality in Solidworks.

Tunnel ventilation design and calculation by PIARC method

In recent years Contemporaneous with the advancement of technology, special consideration needs to transport infrastructure has been raised. One of the main methods of transportation is road and rail transportation. The main feature of these methods of transportation is their generality, which requires special attention to details of design and construction.

Iran also has developed tunnel-digging recently issues related to tunneling, which has been of particular importance and the Resalat tunnel in Tehran, the first tunnel ventilation design project and control system was undertaken.

Design and Simulation of road and rail tunnel ventilation

The new drilling techniques and TBM devices have led to the possibility of digging long tunnels in less time than usual. One of the requirements for digging long tunnels is proper ventilation. The most common method of urban tunnel ventilation is longitudinal ventilation using jet fans.

To cause proper and healthy ventilation in tunnels, additional equipment, correctly design, and detailed calculations of pollutants and environmental conditions are needed.

 

 

To carry out tunnel ventilation computing feasibility studies, some processes must be performed regularly and in a particular order. To basic acquaintance with the tunnel ventilation calculation process, the main steps of the process, will be mentioned as followed:
- Finding out technical drawings and geographical position of the tunnel
- Studying the Climatic traffic characteristics of the region and view
- Studying the status of pollutants produced by vehicles and analysis of traffic statistics
- Calculations to determine the required flow rate for ventilation in traffic and fire mode
- Studying different methods of ventilation and selection of the appropriate method
- Flow simulation inside tunnels with Fluent, SES, and flow works software
- Figuring out all ventilation equipment’s on the chosen method, along with Technical Specification
Araco by having the suitable knowledge, work experience in the field of tunnel ventilation and utilizing Finite element flow simulation techniques is present to carry out projects in road and rail tunnel ventilation design with high certitude and quality.

Parking (Car park) Ventilation by Jet Fan

Construction and operation of commercial and office complex are highly booming, according to the optimal use of existing spaces in major cities. Due to the compression of space in such complexes, parking’s are designed with the assumption to use the most space possible. With large numbers of cars in car-park and enclosed spaces, it will be certainly necessary to design a very powerful ventilation system.
Design and implementation of the ventilation system are necessary for enclosed parking and car park, because of vehicle density. During normal operation in a car park, vehicles produce pollutant gases like carbon monoxide and NOx may cause serious damage to people inside the parking lot. There is also another risk in car parks, which is the possibility of fire. Considering the enclosed area inside the parking’s, the Incidence of fire will produce deadly gases and a huge amount of smoke. According to this situation, parking ventilation systems must have the capability to control the smoke and deadly gases and provide the required time for people to escape from danger. 

Air flow diagram inside a parking 

The old method for parking ventilation was using ventilation ducts in the roof. This method causes many limits in design and operation and in a fire situation, ventilation was not good enough.
New technology in this field is the application of jet fans for normal ventilation and smoke extraction in case of fire in parking. In fact, this technology represents the most innovative and cost-effective alternative to traditional ducted mechanical extraction systems. Carefully managing the project in all its development stages, which requires the fundamental use of fluid dynamics calculation programs - CFD - and also ensures that the system is working correctly. The jet Fan system provides either normal ventilation and can also be provided for smoke extract in case of fire in the parking lot.
After the final design, the performance of the jet fan can be evaluated using CFD in normal operation. Also by using PyroSim and FDS software the function of the installed jet fan could be tested during a simulated fire.
PyroSim is a graphical user interface for the Fire Dynamics Simulator (FDS). PyroSim helps companies to create and manage the details of complex fire models.

Heat transfer simulation and analysis

Heat transfer simulation

Transfer of heat from high temperature source to low temperature source is called heat transfer. The heat transfer can also take place within the system due to temperature difference at various points inside the system. The difference in temperature is considered to be ‘potential’ that causes the flow of heat and the heat itself is called as flux.

 

Heat transfer methods

In heat transfer fundamental, there are three modes of heat transfer between two objects: conduction, convection and radiation.

These methods have been described below:

Conduction: The transfer of heat between two solid bodies is called as conduction. It depends on the difference in temperature of the hot and cold body.

Convection: The transfer of heat between a solid surface and the liquid is called as convection heat transfer. Convection can also take place between two types of fluids like gas and liquid and also inside a fluid.

Radiation: When two bodies are at different temperatures and separated by distance, the heat transfer between them is called as radiation heat transfer. In case of the conduction and convection heat transfer there is a media to transfer the heat, but in case of the radiation heat transfer there is no media. The radiation heat transfer occurs due to the electromagnetic waves that exist in the atmosphere.

You can see all types of heat transfer modes in following picture.

Heat transfer analysis is one type of the CFD simulations. This type of CFD simulation is focused on calculating the rate of heat transfer inside and outside of a system.

Heat transfer simulations is a powerful tool to estimate the thermodynamic condition inside an industrial process and system. This type of CFD simulation can be used for:

PCB heat transfer simulation and analysis

Heat exchanger simulation and analysis

Reactor simulation and analysis

Electric board simulation

Engine heat transfer simulation

And …

Aerodynamic simulation

Aerodynamics is the study of air motion and movement, especially when and where the air contact with a solid. Aerodynamic is a sub-field of fluid dynamics (mechanical engineering) and gas dynamics, and many aspects of aerodynamics theory are common with them.  The term aerodynamics is often used with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air.

The rules of aerodynamics explain us how an airplane is able to fly. Anything that moves through air reacts to aerodynamics. Aerodynamics acts on cars, trains, ships and even motorcycles since air flows around them.

There are four main forces in aerodynamic which are lift, weight, thrust and drag. These forces make an object move up and down, and faster or slower.  The aerodynamic forces do not just apply to moving objects but also it applies to buildings and structures by wind. So the aerodynamic application is not limited to transportation.

The building and environmental aerodynamics is dealing with fluid flow in the atmospheric boundary layer. Emphasis is given to the analysis of wind flow within the influence area of buildings and to the resulting wind loads on buildings and structures as well as to the study of the wind comfort and pollutant dispersion in urban areas.

CFD simulation offers the ability to conduct comprehensive, automated, multi-point optimization of designs. This process allows engineers to automatically optimize a design to a given set of performance parameters and can be used to minimize drag, or maximize mass flow or lift forces to given targets.

Aerodynamic CFD simulations includes:

- Car, Train, Ship Aerodynamics

- Drag reduction and performance optimization

- Structure Wind Load
