| Abstract: | Pressure drop in basic eqllations of particle-fluid two-phase flow is reformulated in this paper by coupling the partial pressure of granular flow to the partial pressure of the fluid,resulting in the unification of different formulating approaches used currently.Drag coefficients corresponding to different formulations of pressure drop are also discussed to elucidate the relationship between drag coefficient and pressure formulation. |
