Abstract

A modified model based on the turbulent kinetic energy equation is used to predict the recirculating swirling flowfield. The model includes the wave and oscillation nature of the swirling flow and redefines the energy budget in the turbulent kinetic energy equation. This brings about improvements in the recirculation zone as well as the recovery region, as compared with the results from models used by Rodi and Launder et al. of the Richardson number type corrections in the dissipation equation.
