| Abstract;The purpose of this study is to discuss the aerodynamic characteristics of athletic spike shoes using wind tunnel test and computer fluid dynamics (CFD). Wind tunnel tests with the full size athletic spike shoes with upper cover and that without upper cover were carried out to measure the aerodynamic forces (drag, lift and side force). It was found that the drag force of the upper covered athletic spike shoe in the case of attacking angle to be 0deg. was 1.24N, that of attacking angle to be 35deg. was 2.51N, that of attacking angle to be 90deg. was 3.50N and that of un-upper covered athletic spike shoe in the case of attacking angle to be 0deg. was 1.04N, that of attacking angle to be 35deg. was 2.23N, that of attacking angle to be 90deg. was 3.28N. An incompressible steady-state analysis was performed using the finite volume method based on fully unstructured meshes with a commercial CFD code (FLUENT6.1, Fluent Inc.). It was also found that the drag force of the upper covered athletic spike model was smaller than that of the un-upper covered athletic spike model. These results suggest that the drag force of the upper covered athletic spike shoe is about 10 percent smaller than that of the un-upper covered athletic spike shoe. (author abst.) |
