抜粋

Appropriate LES guidelines for the pedestrian wind environment in urban areas are being established by a working group from the Architectural Institute of Japan. In this study, large-eddy simulations were conducted for the flow field around an isolated building and within a cubic building array to clarify the influence of various computational conditions on turbulent statistics. First, a cross comparison study was performed by examining both experimental and large-eddy simulation (LES) results for various computational grid arrangements, sub-grid scale turbulence models, spatial derivation schemes (for the convection term), and convergence criterion for a coupling algorithm relating the flow and pressure fields in the flow field around an isolated building. Next, the appropriate computational conditions, obtained from the LES for flow around an isolated building, were applied to the LES for flow within a building array.
