摘要
Abstract
A spout-fluid bed gasifier was built up for gasification of coal. The effect of wide sieve particles on flow characteristics of the spout-fluid bed was analyzed through numerical simulation methods. Unsteady Eulerian multi-phase flow model and the standard k-ε turbulence equation were adopted in numerical simulation, and using the user defined function (UDF) writing out wide sieve particles model. Results show that in dense-phase different size particles appear stratification, the fluid dynamics of spouted fluidized bed was influenced by particle size distribution and energy dissipation and the transfer between particle.关键词
