Abstract

The flow of fluid with suspended particulate matter is encountered in many different fields. Typical examples occurring in nature are dust storms, forest-fire smoke and the dispersion of solid pollutants in the atmosphere. Many processes in industry utilize gas particle flows, such as transportation of pulverized materials in pneumatic conveyers, separation and classification of particles in cyclone and other particles in cyclone or other separators, fluidization in chemical reactors, and combustion of powered fuels in combustion chambers. In addition, flow of fluid with suspended solid particles has various applications to MHD generators, solid propellant rockets, laser-Doppler anemometry and blast waves moving over the Earth’s surface.
Among a few study relating to two-phase flow, so far reported in the literature, no consulted effort has been made to study the particle-particle interaction and heat transfer aspect. The model discussed here is capable of simulating such two-phase flow (Fluid with SPM) phenomena and also able to reveal the details of internal processes viz. incompressible, compressible and turbulent mixing of a particulate suspension. This model has twice the number of differential equations as that for clear fluid model. The particle-fluid, particle-particle interactions lead to stronger non-linear differential equations, which can be solved by utilizing numerical method. The present model has a great potential for further development in the establishment of rational mathematical model for two-phase flow and heat transfer phenomena.
