Abstract

Fluctuating Wind Boundary Condition (FWBC) is compared against a Steady Wind Boundary Condition (SWBC) to determine their suitability in the investigation of air flow and pollutant dispersion processes in urban street canyons. Numerical simulations are performed using Large Eddy Simulation (LES) and it is observed that a FWBC inlet profile produces different outcomes when compared to wind tunnel (WT) measurements and previous published data using SWBC. The FWBC generated in the present study produces more realistic results representing real urban conditions as meteorological data show fluctuations in wind speed and direction at all times.
