Practical LES for estimation of wind pressure on high-rise building located in urban district

Abstract

For estimation of wind load by CFD, number of inflow wind direction, ensemble number, and integration time increase calculation loads. Thus, practical method is necessary for CFD. This study clarifies the accuracy of wind pressure by LES at reduced grid number. As a result, peak wind pressure coefficient underestimated at the lower part, corner and roof of high rise building, but the tendency of local wind pressure and force on target building is reproduced in the case at reduced grid number.
