Abstract
Coupling the finite volume method (FVM) and the moving-particle semi-implicit (MPS) method, a conservative hybrid method is proposed for simulation of incompressible interfacial flow. In this hybrid method, bulk flow is resolved using the multi-moment constrained interpolation profile (CIP) FVM while the interface region is rendered using moving particles calculated by several enhanced MPS schemes. A new boundary condition is developed for particles located on the boundary of the interface. Numerical particles in the MPS method are used to determine the density of each mesh cell and the conservation of mass is guaranteed by a volume-fraction remedy procedure. The approach allows accurate interface tracking without diminishing numerical efficiency. Several benchmark simulations are conducted to demonstrate the accuracy and efficiency of the proposed hybrid method.
