Abstract

CIP (constrained interpolation profile) is one of the CFD (computational fluid dynamics) methods developed by Japanese professor Takashi Yabe. It is used to simulate 3 phase problems including air on the surface, liquid and structure in solid form. To check the validity of CIP theory, experiments with different problems have been implemented and obtained very positive results. This proves the correctness of the CIP method. Based on the need of simulation of wave structure interaction (water wave with float of seaplanes, wing in ground effect crafts, piers, drilling, casing ships...), this paper applies the theory of CIP method to find the answer to the problem of 2D simulation via a obstacle. Objectives to do are understanding the physics, finding out the differential equations describing the phenomenon, then proceeding discrete, setting up algorithms and finding out solution of the equations. This paper uses Matlab software to write programs and displays the results.
