Prediction of turbulent transition in boundary layers using the turbulent potential model

Abstract

The turbulent potential model is applied to predict transition in flat plate boundary layers. The turbulent potential model is a non-equilibrium RANS model with the predictive capabilities of a Reynolds stress transport model but the cost and complexity of more popular two-equation models. It has been applied to numerous fully turbulent flows with great success. In this work the model is applied to bypass and natural transition of flat plate boundary layers. We include the effects of acoustic noise and pressure gradients and demonstrate the model's ability to relaminarize.
