Numerical Simulation Using Near Wall K-.EPSILON. Turbulence Model for Flow in Intake Port of Automotive Engine.

The near wall K-e turbulence model of Chien is applied to simulate the flow in the intake port of an automotive engine. In order to investigate the improvement in prediction accuracy due to incorporation of this model, the effects of changes in port curvature on the mass flow rate were computed, and the predictions were compared to our computational results without turbulence model and test results. It is demonstrated that Chien's K-e model has the potential for improving the prediction accuracy of the flow in an intake port.
