Improving boundary-layer separation prediction by an IDDES turbulence model using a pressure-gradient sensor
Benjamin S. Savino, Kevin Patrick Griffin, Bumseok Lee +3
This work extends a pressure-gradient sensor for boundary-layer separation originally developed for the shear-stress transport Reynolds-averaged Navier-Stokes (RANS) model (…

Improved pressure-gradient sensor for the prediction of separation onset in RANS models
Kevin Patrick Griffin, Ganesh Vijayakumar, Ashesh Sharma +1
We improve upon two key aspects of the Menter shear stress transport (SST) turbulence model: (1) We propose a more robust adverse pressure gradient sensor based on the strength of…
