Numerical Simulation of Mean Wind Speed Profile Under Different Building Conditions

Abstract:

Based on the computational fluid dynamics method （CFD）， the wind field cases with different building environment parameters were systematically simulated and the variation of mean wind speed profile exponents was discussed. The results show that the average building height has a greater impact on the mean wind speed profile exponent than the building density. An empirical formula for the mean wind speed profile exponent with the average building height and building density is proposed as independent variables.
