Since the standard κ-ε model used to predict the strongly swirling flow leads to a large deviation from experimental results, it is necessary to introduce modification to the standard κ-ε model. Based on the algebraic Reynolds stress model and Bradshaw’s turbulent length scale modification conception, we present two modified κ-ε models. To investigate the behaviour of the modified turbulence models, they are used to predict two representative turbulent swirling flows. The computational results, after compared with the experimental data, show that the modified κ-ε models substantially improve the prediction of the standard κ-ε model for the turbulent swirling flows.
