Study on Application of Lagrangian Numerical Simulation to Fluid Dynamics in Sports Science

摘要

This paper describes a pioneering work of practical application of a vortex method in the field of fluid dynamics in sports science. The vortex method developed by the present authors is one of vortex element methods based on the Biot-Savart law, and it is known that the method provides a Lagrangian simulation of unsteady and vortical flows, -dimensional, complex and unsteady flows around an isolated sprinter were calculated. From the results of the present study, it has been confirmed that the vortex method is available and useful for research of the fluid dynamics in sports science.
