Computational Analysis for Motions of Rugby Balls Interacting with Air Flows

抄録

Computational simulations of motions of rugby balls are presented. Fluid-structure interaction plays an important role in rugby ball motion. An incompressible Navier-Stokes equation is solved on a Cartesian coordinate system. The rugby ball motions are calculated simultaneously using Newton’s equation of motion for transitional motion and Euler’s equation of motion for rotation. Computational results for screw and high punt kick cases are compared with those obtained from experiments.
