CFD Simulation
Computational Fluid Dynamics (CFD) is the analysis of systems involving fluid flow,
heat transfer, chemical reactions by using computer based simulation. CFD is used
for a wide range of industrial and academic research areas, such as:
- Airplanes and vehicles aerodynamics.
- Internal combustion engines and turbomachinery.
- External and internal environment of buildings: wind loading, ventilation and
fire dynamic simulation.
- Biomedical and pharmaceutical applications.
- Heat exchangers design.
- Mixers and chemical reactors.
CFD uses generally the finite volume method where the computational domain is divided
into a number of smaller sub-domains called elements or cells which constitute the
mesh. The continuity and momentum equations (Navier-Stokes equations) are hence
solved in each cell using appropriate numerical methods and schemes. The flow can
be modeled either laminar or turbulent. When the flow is turbulent, a turbulence
model is used depending on the flow nature.
WTA uses the latest software for CFD simulation, and has already done projects requiring
Smoke Management, Ventilation, Thermal Comfort and Wind Tunnel Test.
