原始语种摘要: A stroke-analysis system based on a CFD (Computational Fluid Dynamics) simulation has been developed to evaluate the hydrodynamic forces acting on a swimmer’s hand. Using the present stroke-analysis system, a stroke technique of top swimmers can be recognized with regard to the hydrodynamic forces. The developed analysis system takes into account the effect of a transient stroke motion including acceleration and a curved stroke path without using assumptions such as a quasi-static approach. An unsteady Navier-Stokes solver based on an unstructured grid method is employed as the CFD method to calculate a viscous flow around a swimmer’s hand which can cope with the complicated geometry of hands. The CFD method is validated by comparison with experiments in steady-state and transient...
