Simulation Optimization of DPM on Gas-Solid Two-Phase Flow in Complex Pipeline Flow Field

Zhang Tao;Li Hongwen;School of Electrical Engineering and Automation,Tianjin University;School Office,Northeast Petroleum University;  
General discrete phase model(DPM) simulation on gas-solid two-phase flow is now widely employed. In order to improve its accuracy on pipeline throttling with complex flow field, based on analysis combined gas flow field and forces acting on solid phase particles, four optimization measures about the general DPM model are proposed,which include gas inlet velocity model, particle drag model, collision of particles with internal surface of pipeline and reasonable choice of each force on particles. The optimization of general model is achieved by calling Fluent related macro and compiling user defined functions(UDF) program.Experiments verified that the accuracy of the optimized DPM model is significantly superior to the general model,as is shown in the following four aspects: the simulations of the two-phase flow gas velocity conversion interval and the gas critical velocity of particle sedimentation,which increased by 55% and 50% respectively in the optimized model; what is more, the optimized model obviously has more accuracy advantage on local resistance loss in experimental pipe and particle velocity distribution simulation. Through the contrast of experiment and simulation, the optimization is proved to be successful, and it is concluded that the method of optimization is versatile for other pipeline with complex flow field and has practical engineering value.
