A New Model Coupling Interface Tracking Methods and Two-Fluid Model for Simulation of Incompressible Gas-liquid Two-Phase Flow
A model coupling two basic models, the model with interface tracking method and two-fluid model, for simulation of incompressible gas-liquid two-phase flow is proposed. A united solution frame shared by the two basic models is built. In the shared solution frame, the Navier-Stokes equations of the two basic models can be dealt with in a uniform form. In the proposed model, there are three phases, which are divided not only by physics but also by the length scale of interface, including the liquid phase, the large-length-scale-interface gas phase and the smalllength-scale-interface gas phase. The special treatment named by void fraction redistribution is adopted for the special grids which contain all three phases. Based on the united solution frame, MCBASIMPLE algorithm is used to solve the equations. Two problems are calculated to show that the proposed model has the merits of the two basic models.
