摘要

A hybrid k‐ε turbulence model, based on the concept that the modification of anisotropic effects should not be made in the flow regions inherent to small streamline curvatures, has been developed and examined with the swirling recirculating flows, with the swirl levels ranging from 0·6 to 1·23 in abrupt pipe expansion. A fairly satisfactory agreement of model predictions with the experimental data shows that this hybrid k‐ε model can perform better simulation of swirling recirculating flows as compared to the standard k‐ε model and the modified k‐ε model proposed by Abujelala and Lilley.
