2D NUMERICAL MODEL OF MULTIPHASE FLOW WITH DYNAMIC BEHAVIOR OF MULTIPLE BODIES
A two-dimensional numerical model of multiphase flow with dynamic behavior of multiple bodies “DOLPHIN-2D is newly developed in the present study by means of a CIP method and an extended SMAC method based on the irregular grid method. The governing equations are divided into two steps of an advection step and a non-advection step using a timesplitting method. The CIP method is employed to compute the hyperbolic equations at the advection step with high accuracy, while the equations at the non-advection step are solved using the extended SMAC method so as to be able to compute compressible and incompressible fluid flows simultaneously. As a result of the application of the model to some collision problems between collapsing water and multiple bodies, it is confirmed that the model can simulate multiphase flows with dynamic behavior of multiple rigid bodies appropriately and track the interfaces between different phases without setting complicated boundary conditions among solid-gas-liquid phase.
