SIMULATION OF GAS-SOLID TWO-PHASE FLOW IN HORIZONTAL PIPE

摘要

References(8) Cited-By(9) An ellipsoid bouncing model, previously presented to express the irregular bounce of particles on a duct wall, was extended to simulation of gas-solid suspension flow in a circular pipe. Simulated results were compared with experiments in terms of concentration distribution, particle velocity, additional pressure drop and frequency of particle collisions with the pipe wall. If the mean observed deformation, ηob, was taken as the value of the parameter, the mechanism of particle motion was explained for the most part by the simulation.
