About Computational Fluid Dynamics - CFD (continued) Prevailing environmental conditions, particularly within inner city environments can also impact the conditions within a Car Park. Fläkt Woods can take into account these external conditions within their CFD modelling. Fläkt Woods can also design full smoke control solutions and provide comprehensive fire modelling to prove the systems. There are two types of Smoke Control System as described within BS7346 Part 7, the first is to achieve tenable conditions for the fire brigade to enter the Car Park, locate and tackle the fire and the second is to assist means of escape for Car Park occupants. Image above showing a transient combustionmodel of a car stacker system. Images above showing how an engineeering approach improves a design - by removing the supply in the ceiling, smoke is no longer dragged to low level giving better visibility with the car park.                     Main Features: • Complex geometry modelling of any environment • Advanced meshing techniques • Steady state and transient analysis • Pollution and Emergency ventilation simulation and analysis • Advanced state of the art design fire modelling and simulation including both inert and  combustion modelling techniques. • Isosurfaces of smoke and temperature • Local Mean Age of air (LMA) - used to access ventilation performance and quickly compare design solutions. • Graphical outputs for analysis include: - Air speed profiles - Air velocity profiles - Air velocity vectors - Streamline animations - Contaminant and / or toxicity profiles - Temperature profiles - Visibility profiles - Smoke visualisation                                            THRUST FAN SYSTEM IS DESIGNED TO MEET EACH CUSTOMER PROJECT, USING STATE-OF-THE-ART CFD ANALYSIS AND BEST PRACTICE TECHNIQUES
