Description
Summary:Two-dimensional water entry problems have been solved by a constrained interpolation profile (CIP) method. This paper presents the further development of this numerical method using staggered grids and a parallel computing algorithm. In this work, the multi-phase problem governed by the Navier–Stokes equations was solved by a CIP-based finite difference method. The interfaces between different phases (solid, water and air) were captured using density functions. A parallel computing algorithm based on the message passing interface method and a domain decomposition scheme were implemented to speed up the computations. The effect of the domain decomposition scheme on the solution and the speedup performance were studied. Validation studies were carried out for the water entry of a wedge, a ship section and a circular cylinder. The predicted slamming forces and pressure distribution were compared with experimental results and other numerical solutions.
