摘要：We developed a new immersed boundary method which has various advantages, such as accuracy, flexibility, and rapidness combining with the level set method. We numerically demonstrated some typical examples, such as flows around a sphere, an ellipsoid, a flapping ellipsoid, and a windmill. We calculated coefficients of drag in those problems and visualized vortical structures and Powell sound sources for the various Reynolds number and then compared our results with some previous researches.
