GSMAC有限要素法による立方体キャビティ内の非定常三次元流れの解析 : Re=1000とRe=3200の場合

抄録

In previous simulations the modified, GSMAC method which is more applicable to in-out flow problems, was proposed. In the present paper, however this scheme is extended to the three-dimensional analysis. As an example, flow in a cubic lid-driven cavity which has many authorized experimental and numerical results, has been calculated at the Reynolds numbers 1 000 and 3 200. Consequently, the velocity profiles are in good agreement with the spectral method at Re=400 and 1 000 [4], and the TGL vortices, which give a three-dimensional effect, have been simulated.
