CFD simulation of the must flow in a hydrocyclon

Abstract

The hydrocyclone is an equipment for clarification and separation of the solid particles, in suspension in a liquid, based on the density difference. The flow description in a hydrocyclone is much more complex compared to a cyclone for gaseous dispersions, as it appears three liquid-gas-solid components (the appearance of the air core), although the overall separation mechanisms are similar. Over time, many experiments have been carried out to determine the flow in a hydrocyclone.The proposed experimental methods are expensive and difficult to implement in technical terms, being limited to a dispersed liquid phase.Given these deficiencies, in the last two decades, have been developed models of fluid flow dynamics (CFD) based on flow fundamentals.The paper aims is to CFD simulate the flow of must during the working process of a hydrocyclone.
