Evaluation of Inhomogeneous Model for Computations of Gas-Liquid Multiphase Flows

In this paper, an evaluation of inhomogeneous model for computations of gas-liquid multiphase flows was presented. The gas-liquid multiphase flows in the bubble column and the flows around the plane were simulated with the homogeneous and inhomogeneous model respectively, and the numerical results were compared with the experiment. It is shown that: due to the consideration of the interaction between the two phases, the inhomogeneous model can calculate the force of the gas phase more accurately and simulates the details of transient flows well. The periodic fluctuation of the bubble hose in the column, the break and floating of the bubble around the plane are captured. Meanwhile it can better predict the velocity distribution and the hydrodynamic unsteady characteristics.
