- •
A detailed comparison between the k−τ and k−ɛ turbulence models is presented.
- •
The k−τ model has a higher numerical accuracy in homogeneous and stratified boundary layer flows.
- •
The k−τ and k−ɛ models typically approximate the converged result closely only for more than 100 vertical grid cells.
