The Study of Relationship between Velocity and Drag Coefficient of Swimmer using Computational Fluid Dynamics

Swimming is one of the sports that has developed fundamental changes in all of its stages by using the latest scientific and technical developments. Today, computational fluid dynamics is a powerful tool for analyzing sports in which velocity plays a major role. In this paper, we have examined the relationship between swimmer's velocity and drag coefficient. For this purpose, a swimmer with different velocities has been modeled in FLUENT software (V=1 m/s, V=1.5 m/s, V=2 m/s) and then drag force and drag coefficient have been calculated in these three cases. The results of the model solution have been presented as pressure changes, velocity, and coefficient tables and drag force.
