A numerical solution for gasparticle flows at high Reynolds numbers
Abstract
Predicting the fluid mechanical characteristics of a gassolid twophase flow is critical for the successful design and operation of coal gasification systems, coal fired turbines, rocket nozzles, and other energy conversion systems. This work presents a general gridfree numerical solution which extends a numerical solution of the NavierStokes equations developed by Chorin to a solution suitable for unsteady or steady dilute gassolid particle flows. The method is applicable to open or closed domains of arbitrary geometry. The capability of the method is illustrated by analyzing the flow of gas and particles about a cylinder. Good agreement is found between the numerical method and experiment.
