LES for Flow and Pressure Field around a High-rise Building in High Density Urban Areas

Abstract

It is required to clarify the effect of the turbulence field formed by surrounding buildings for wind load estimation of high rise building. Also, its wind load can become high due to surrounding pressure field. This study clarifies the influence of the turbulence field formed by surrounding buildings and pressure field around claddings by analyzing high-rise building located in high-rise urban area. As a result, flows separated from windward buildings flows come into the space surrounded by other buildings and the negative pressure is intensified on the north-west upwind point of 23^rd floor.
