PyroSim and FDS Simulations

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.
PyroSim and FDS are both using as main software to simulate the fire reaction in different environments like Building, parking lot, Subway, Tunnel, Cinema, Commercial office complex  and …
Using PyroSim we could define smoke detectors and sprinklers in 3D model, in order to examine the current design in case of fire with both software.
Meanwhile it is possible to link PyroSim results with Pathfinder software which is advanced movement simulation combined with high-quality 3-D animated results, gives reliable answers.

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, this is a fluid unlike solids are not able to withstand shear stress. Knowing this, it is planned equations for fluid motion analysis. This equations to respect both the British and the French mathematician called Navier-Stokes equations. CFD - Computational Fluid Dynamics - in fact is 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 with 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 in 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

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

  • Analysis and simulation of tunnel ventilation

  • Analysis and simulation of heat exchanger

  • Analysis and simulation of chimneys

  • Analysis and simulation of pumps

CFD has been playing an increasingly important role in HVAC and ventilation, following its continuing development for over a quarter of a century. The information provided by CFD can be used to check the impact of building exhausts to the environment, to predict smoke and fire risks in buildings, to quantify indoor environment quality, and to design natural ventilation systems.


CFD data center

CFD application in HVAC and ventilation can be classified as:

·         CFD analysis for air conditioning in Buildings, Stadium, Cinemas, Hotel, Hospital and …

·         CFD simulation for HVAC inside Server room and Data center

·         CFD simulation for air conditioning inside class room and companies

·         CFD simulation inside tunnel and metro stations

·         CFD simulation inside parking lot and multi floor parking

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 mode

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 …

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.

Car wind tunnel

Vehicle aerodynamic


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.

building aerodynamic


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
