Numerical Simulation of Solid-Liquid Two Phase Flow in Horizontal Circular Pipe Based on CFD

摘要

Aiming at the complexity of solid-liquid two phase flow theory analysis and experiment operation as well as the theory calculation model which fails to be widely applied due to its strong experience dependency, this paper hereby brings forward a numerical simulation of Euler-Euler two fluid model and carries out analyses on the pressure drop and flow-pattern change law of solid-liquid two phase flow under solid volume fraction and velocity change on the basis of analysis on experiment data and calculation model. According to the experiment result, CFD numerical simulation result is perfectly consistent with the computed result and measured data with regard to analysis on the pressure drop change law, but CFD numerical simulation result shows a comparatively smaller error than the measured data, it can well reflect the slurry flow law inside the pipeline and provide certain references for researches on solid-liquid two phase flow of horizontal pipeline.
