壁面モデルを用いた格子ボルツマン法によるLES解析

抄録

This study presents a new scheme of the wall modeled LES. The present approach uses the specular reflection boundary condition with an imposed wall stress from the wall model. To validate the scheme, calculations of turbulent channel flows and flows around a square cylinder were performed. The obtained results showed an encouraging agreement with DNS data in the channel flow. However, in the flow around square cylinder, the results suggest farther improvements.
