| Abstract: | The hydrodynamics of non-fluidized gas-particle flow through aninclined pipe and an orifice is studied by using the theories of multiphase flow and particulate media mechanics. A series of dynamic differential equations is developed to correlate the gas pressure, interparticle contact pressure, voidage with the properties of gas and particles, the geometry of the bed, and the condition of operation. A numerical method of the dynamic differential equations and an integral method of the simplified dynamic differential equation, which are used to calculate the particle flow rate through an orifice, are also established. The theoretical prediction is in good agreement with the experimental data. |
