Abstract

This paper is intended to newly construct a two-dimensional multiphase flow numerical model “DOLPHIN-2D” withsolid-gas-liquid phase interaction based on a CIP method and an extended SMAC method, taking into consideration a Lagrange particle-based method for the dynamic motion analysis of multiple rigid bodies. The constitutive law of Bingham fluid is, moreover, introduced into the DOLPHIN-2D in order to compute non-Newtonian fluid dynamics. Theutility and validity of the model is verified by applying it to bore-floating body collision/dam-break problems and comparing with the laboratory experiment. The results reveal that the model can appropriately simulate not only thedynamic behaviors of complex shaped multiple bodies but also non-Newtonian fluid motion.
