Abstract
This paper presents the implementation of the immersed boundary method to the CIP multi-moment finite volume method to deal with solid body in fluid flows. The presence of the solid body and its effects up on the surrounding fluid are formulated by additional forcing to the momentum equations, and the divergence is computed from the effective flux where the fluid fraction on the edges of each mesh cell is taken into account. Furthermore, we have extended the method to be applicable to moving boundary as well as thermal boundary simulations. The proposed method has been extensively validated by a wide spectrum of numerical tests. With the competitive numerical results, we believe that the present method can be an efficient and practical tool to simulate fluid/solid interactive flows in various engineering applications.
