Separation effects in gas-particle flows at high Reynolds numbers
Abstract
A general numerical solution is presented which extends a numerical scheme for gas flow to a solution suitable for dilute gas solid particle flows over a much wider range of conditions and geometries. The proposed method is designed to solve the time dependent equations but may be used in the steady state case as well. An exact solution for the inviscid two phase flow near a stagnation point is also presented. A transformation is used that reduces the partial differential governing equation to a second order linear differential equation. The numerical method is applied to the flow of gas and particles about a cylinder. A cutoff value is found in particle size which determines particles that do not impact with the cylinder but are deflected around it.
