H-type of single-block grids is commonly used for blade cascades, because the grids can be simply generated However, the mt important iegion around a leading edge has large grid distoffion including a singular point Therefore, it is considered that sufficient calculation accuracy cannot be thtained. In this study the grids are arranged by a multi-block grid and an overset grid which are made of O-grid around a blade and H-grid between blades, because the distortion of H-grid is improved by using an O-grid arotmdablade. The three type topologies are compared ith the experimental results, and the differences of the characteristics are investigated The results of computational fluid dynamics are well in agreement with experimental results for three grid topologies, and even H-grid it became clear that the accuracy is practically sufficient
