1217 遊泳する魚周り流れの数値解析

抄録

It is well known that swimming fish has high efficiency. However, there are unknown matter of swimming fish. In order to solve the flow, numerical method using deformation grid is developed in this investigation. In grid generation, spline interpolation and transfinite methods are employed. And Laplacian operator is used to smooth the generation grid. Artificial viscosity is treated as implicitly for computational stability. As the results of this investigation, it can be computed around the swimming fish.
