Computation of Turbulent Flow in a Cyclone Chamber with a Reynolds Stress Turbulence Model.

Abstract

The cyclone separator is widely used in industrial applications as a method for dust removal from gases. In this chamber, a very complex flow field is formed, involving the interaction between high-swirling velocity and turbulent stress field. The problem of predicting this kind of flow is solved by applying a Reynolds stress transport model. Furthermore, we perform a calculation using a K-e model in order to compare with the predicted performance. It is shown that the predicted results obtained by the Reynolds stress model are in good agreement with those of measurements.
