This month we look at why CFD is needed

Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyse problems that involve fluid flows.
CFD modelling has become a very common tool in the field of engineering and its broad use expands over the automotive, aeronautical, structural, mechanical and fire engineering fields to name a few. The reason for the dependence on CFD is because it allows for a product or system to be designed and ensures that it works prior to building and installing it. This means that the design and installation process becomes much more cost effective and less time consuming.
The processes for modelling are numerous and include: turbulence, buoyancy, thermal radiation, flame spread, pyrolysis, combustion and the tracking of specific gases such as oxygen, carbon dioxide and smoke.
There are some cases in fire engineering where doing hand calculations or zone modelling is not sufficient as the flow effects or building geometry may be too complex to be solved by these methods. CFD modelling is now providing answers for these complex calculations. The results then set the benchmark of how the system should operate and what the resulting effects will be. The new system and its effects can be verified upon commissioning of the installed equipment in the building.
