Wind Influence in Numerical Analysis of NSHEV Performance

This paper treats on the subject of including wind as a boundary condition in CFD analysis used in Fire Safety Engineering. Adverse wind effect is observed mostly on the performance of natural smoke and heat ventilators – and often is included in numerical studies performed by engineers. This paper provides with general guidelines on the Computational Wind Engineering, as well as to relevant references. Paper emphasizes on the necessity of building large enough domain and performing an angle sensitivity analysis, to determine the worst wind conditions for the vents. Only then the fire-related CFD/CWE coupled analysis may be performed, with reasonable and believable results.
