Abstract
This paper assesses the effectiveness of a modified cubic low-Reynolds-number two-equation turbulence model in predicting a number of complex turbulent flows including a turbulent impinging jet, turbulent flow in a curved duct, turbulent heat transfer in a three-dimensional ribbed passage and turbulent heat transfer in a passage with sudden contraction. The numerical results clearly demonstrate that marked improvements in flow and thermal predictions can be achieved by using the cubic nonlinear model as compared with the linear model.
