Abstract

This study discusses the application of LES (Large Eddy Simulation) by BCM(Building Cube Method) to prediction of wind velocity and pressure around the building. First, BCM-LES is applied to flow and pressure field around square cylinder in turbulent boundary layer. The computation result shows that very fine structures in the wake region are shown by the calculation using the locally high resolution grid system of BCM, and the flow field around square cylinder is corresponding to the computation results in the previous study.<br>Next, the BCM is applied to flow simulation of real urban area (Domain size:25x12km). As a result of this simulation, the development process of atmospheric boundary layer from coastal area to Tokyo central area is examined. In the calculation, the present numerical model based on BCM-LES shows sufficiently fine structures of turbulent flows with good accuracy by using K computer.
