heat transfer convergence
Hi,
I am performing RANS simulation on jet impingement (full 3D model) with SST tur. model. I am wondering why the heat transfer convergence is so bad, while the momentum and turbulence are good. Thx, Martin |
what are the y plus values ?

Errors in heat transfer are typically 20-40% in turbulence modelling, especially when looking at local heat transfer rates (rather than global heat transfer). It is much harder to get heat transfer right compared to momentum. This is explained in any turbulence modelling textbook.

thanks for reply.
