非圧縮性流体の中心差分法によるCFDプログラムの開発とその検証

(乱流解析への応用)

It was reported previously that applying unsteady Reynolds stress to the right-hand side of the equation of motion had the effect of delaying the divergence of the flow analysis in the circular tube. By changing the value of the Reynolds number to a small value in and around the cell where the value of the unsteady Reynolds stress term applied to the right side exceeded a certain value, the solution no longer diverged and a solution consistent with the conventional experimental results of circular tube turbulence was obtained. Therefore, tube turbulence could be calculated without the use of experimental knowledge.
