Unstructured Grid Convergence Study
Résumé
This paper focus on convergence study of CFD prediction using unstructured grid with our in house finite volume unstructured RANSE solver ISIS-CFD. Computations have been performed with different grid sets generated with different approaches including similar grid generation with unstructured grid generator and adaptive grid refinement. Numerical uncertainty is evaluated with Richardson extrapolation. Results obtained both with wall function and wall resolved approach are compared. It demonstrates that adaptive grid refinement is the most reliable approach for obtaining a grid independent solution.
