Towards pressure gradient sensitive transitional k-kl-omega model: The natural transition for low-re airfoils

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 mi...
