Computational fluid dynamics (CFD) is a branch of fluid mechanics that utilises numerical analysis and data management to analysis and solve problems that involve fluid flow.

CFD modelling is a useful tool in the build environment to study the behaviour of smoke and heat in a building.

Typical examples include the prediction and study of smoke spread in residential and commercial buildings. CFD analysis can be used to specify and design smoke control systems in the form of natural or mechanical ventilation as well as ensuring an optimal and efficient solution to the client.

Computational Fluid Dynamics can also be used to study the build-up of CO exhausts and smoke spread in car park and test the performance of a car parking ventilation system post firefighting operations.
