It is used here to predict the particle-laden flow in the dilute particle concentration in a horizontal channel. The multiphase simulation was carried out in the Eulerian-Eulerian two-phase model with VR-QMOM for the particle phase and for comparison with the more established Eulerian-Lagrangian two-phase flow method. The gas phase is simulated with RANS equations and discretised with second-order upwind spatial numerical schemes. Comparing the predicted particle flows obtained using the VR-QMOM and Eulerian-Lagrangian approaches, the conclusion can be made that the VR-QMOM can successfully predict bouncing multiphase flows with dilute particle phase. Both trajectory crossing and bouncing behaviour and the trend with increasing particle size are reproduced. The two-node VR-QMOM is seen to be an alternative methodology for the prediction of dispersed particle flow problems.
