How to model wind effect?
« on: November 17, 2014, 02:27:43 am »

Hi All,

I need you help. I am trying to model an open carpark and want to model the wind effect through the carpark.

What is the best way of doing this?

On the Environment tab of the Simulation Parameters dialog there is an Initial Wind Velocity option that lets you set a wind vector. If you want something more, FDS6 offers some additional options. Here are some relevant sections from the FDS Users Guide.

Section 6.4.3 "Special Topic: Mean Forcing and Data Assimilation" of the FDS Users Guide describes a MEAN_FORCING option on the MISC line that might give you something beyond the Initial Wind Velocity inputs on PyroSim's Simulation Parameters dialog.

Section 9.1.8 "Special Topic: Turbulence Inflow Boundary Conditions" discusses another wind modeling mechanism relating to turbulence.

Section 9.4 "Special Topic: Pressure Boundary Conditions" of the FDS Users Guide discusses the dynamic pressure option and how it can be used to model enclosed areas.
