HVAC and Ventilation CFD

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.

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 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

· CFD application for indoor farming ventilation

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.

Fire simulation animation in parking using FDS

Using PyroSim (FDS based) software following simulations will be available :

Simulation of fire and smoke in parking and park lot

Fire simulation inside road, railway and metro tunnel

Fire and smoke simulation inside stadium, sport complex, residential complex, hotels, Theater, Cinema

Fire and smoke simulation inside airport ,subway station ,train station

Fire and smoke analysis in factory

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:
