Meshing Techniques & k-omega turbulence model

Hey all,
Question 1 Recently I used three different grid generation technique to simulate for external aero for a simplified model. Those three techniques are 1)fully hex, 2) Fully Tet and 3) Hybrid (Hex close to the wall and Tet everywhere else). I did grid adaptations and achieved grid independence. The final results showed that hybrid mesh gave the closest comparison to experimental data. I used std k-epsilon with non-equilibrium wall model. Why is it so? Hex should give the better results due to minimum skewness in its grid shape. Question 2 How come k-omega turbulence model does not come with a 2-layer wall model option? |
