| Research Abstract |
Based on wave profiles obtained by analysis of image which were captured by a high speed video camera, we investigate the characteristic on development of waves under blow beginning. It was found that the drag coefficients determined by the shear-stress become one-order larger than the experience formula. Further, for unreal pressure oscillation in fluid particles due to MPS method, an algorithm which corrected the source term in the Poisson equation are compared with original MPS method. As a result, we made clear that the oscillation of pressure strongly affects the structure deformation because the fluid force does not accurately act on the elastic body.
