Studying In Floating Ice-liquid Two-phase Numerical Simulation Based On Curvilinear Coordinates

With the rapid development of the computer technology,the mathematic model is adopted more and more when it comes to study in ice-water two-phase flow.The mathematical model has become an important method when studying in the ice-water two-phase flow due to its characteristics of convenience,high efectiveness and low cost. Aiming at sinuous and irregular boundary,the curvilinear grid is generated adopted the technique of body-fited coordinate transform. Based on curvilinear grids,plane two-dimension flow model has been established.Discreting equations based on the Finite Volume Methods(FVM) in this paper.To prevent the pressure oscillation on non-staggered grids,an interpolation method called momentum interpolation is presented to evaluated the cell-face velocity.The contravariant velocity fluxes are used as dependent variables in the paper.The discretization equations were solved using the SIMPLE,SIMPLEC and SIMPLER algorithms.Using this model, velocity of flow in a curved channel was simulated with good fit to the laboratory data. The two-phase flow theory was used to simulate the floating ice particle trajectory with stochastic trajectory model.The simulated results has a certain extent similar with actual process.
