Towards Pressure Gradient Sensitive Transitional k-kL-omega Model: The Natural Transition for Low RE Airfoils
Original language description
The work deals with the development of a pressure gradient sensitive variant of a three-equation RANS model for turbulent and transitional flows. The model is based on the laminar kinetic energy approach by Walters and Cokljat [1]. The revisited model [2] was successfully validated for zero or mild pressure gradient flows with the so-called bypass transition (see e.g. [2]). In the case of natural transition in adverse pressure gradient flows the model usually tends to predict the transition too late, see [3], [4], [5]. The aim of present work is to improve the model for the case of flows with very low free-stream turbulence levels with adverse pressure gradient. As a first step we focus the attention to the onset of linear instability.
