LES around a Realistic City Block Designed Based on a Future City Concept

Abstract

In this study, we discuss the flow field of the realistic city block model planned according to the concept of the future city, in the case of an actual typhoon and a winter monsoon hit. This study applied BCM-LES technique, which enables large scale simulation with high efficient of parallel computing. The fluctuating inflow of the actual typhoon was created by using the method of adding the turbulent component based on WRF-LES. From the computed results, we confirmed that properties of inflow and the location of high-rise buildings affect the flow field and the pressure distribution of target high-rise building.
