摘要

The purposes of this study are construction of viscoelastic model to evaluate the aerodynamics drag and evaluation of textile of suits for sprinter. In previous studies, evaluations by computer simulation for the aerodynamics are almost CFD (Computational Fluid Dynamics). However, the evaluation by CFD is complex and when we evaluate products for sports, the parameter for evaluating should be simple form as possible. Therefore, we constructed the viscoelastic model to evaluate the aerodynamics drag. This viscoelastic model is constructed from mass, elastic element and viscosity element. In this result, we confirmed the variation of viscosity element in textile part. Moreover this parameter represented transition from laminar flow to turbulent flow. These results could give the important suggestion to design of the suit by laminar-turbulent transition, would be the new method to evaluate and create the new concept of the suit for sprinter.
