11 CFD Modelling

Due to the lack of suitable published guidance the use of Computational Fluid Dynamics (CFD) in design of suitable ventilation systems serving loading bays or coach parks, the Smoke Control Association has published a comprehensive guide related to this subject for designers and regulators. The guide should be of use to the designer in producing and running the CFD model and in writing the CFD report. It also provides recommendations on the information to be provided to the approving authority within the designer’s package of supporting information when submitting the CFD analysis for information and/or approval of design intent. The Smoke Control Association is primarily concerned with ventilation design for the removal of smoke and heat as discussed in the British Standard, but, recognising the dual use of systems, this document provides guidance on usage for both smoke and heat removal and vehicle emission ventilation.
