THE 2-FLUID MODEL OF TURBULENT BUOYANT RECIRCULATING 2-PHASE FLOW

Taking refined forecasting model of oil pollution as basic target, thi s paper widely deals with the theory and method of refined simulation of turbulent two-phase flow. The two-fluid model of turbulent buoyant recirculating two-phase flow and the corresponding method of numerical computation are developed in this paper. The motion of each phase is described by a unified multi-fluid model in an Eulerian coordinate sys tem. The laws of turbulent transportation for each phase, and the rest riction of each other between the two phases are completely simulated. The complex two-phase turbulence with buoyancy and recirculating flow is selected to examine numerically. Comparison of the results of nume rical simulation with the experimental data is conducted. Then the for ecasts for oil-water two-phase turbulence are carried out, It has been shown that the results of numerical simulation are satisfactory.
