Hi,
i'm solving impact of swirl genetators on heat transfer in tube. And I'm still not sure with my final choise of k-epsilon realizable turbulent model. I read many discussions where they are compared k-e realizable and SST k-omega. The main problem is that for application of k-omega I need very fine near wall grid for y+ approximately equel to 1. For my conditions, it's about 1*10e-07 m for first cell. Currently, I have first cell equel to 5*10e-5 m with y+<60-120>. My conditions: d=0,008 m, v=3 m/s, Re= 2*10e05, t=300 °C, water Thank you for your possible ideas and suggestions. |
