Abstract
This paper describes a work of practical application of an advanced vortex method for the moving and deforming boundary problems. In this study, a fully coupled methodology is developed for calculation of moving and deforming boundary problems including the flow-structure interaction problems. In order to confirm the applicability of our code, flow simulations around a sprinter and a flexible cantilever circular cylinder were performed. As results of the present study, vortical and unsteady flow features around a sprinter and a flexible cantilever circular cylinder are understood, and unsteady variation of fluid forces corresponding to deformation of body configuration due to the motion are calculated. From the results of the present study, it has been confirmed that the vortex method is available and useful for research of the moving and deforming boundary problems.
