Simulation method of the low-Re flows in the packed bed technological equipment

Abstract

The paper shows the semiempirical method of a numerical simulation of the low-Re flows in the packed bed technological apparatus. The proposed method is based on the Navier-Stokes equations modification by the linear momentum sources equations in the packed bed zones. It is found that the simulation error of the proposed method is not more than 6.2% for low-density finite element meshes. The average value of the simulation error is about 3.0% for all shown cases. It was found that the proposed method simulation error almost independents on the mesh density. In the main, the simulation error is determined by the linear momentum sources equations approximation error. © Published under licence by IOP Publishing Ltd.
