Research on Liquid-solid Two Phase Abrasive Flow Based on the Unified Second-moment

摘要

According to liquid-solid two-phase flow model for the complexity of adaptation, as well as the impact of the concentration of particles, and we put forward a new method of considering the turbulent influence of particle concentration. Basing on the different turbulent control methods of the liquid-solid two-phase flow, we established the unified second-moment turbulence model. Using fluent software can realize turbulence model considering the particle pressure's influence on particle's concentration, and solve the problems of particle concentration and the flow passage control method. The simulation results showed that considering the concentration of particle's influence on the pressure of the solid phase can accurately express the model of liquid-solid two-phase turbulent flow pattern.
