I am simulating flow over blunt body with aerodisk(Compressible flow: Mach -2). I've selected k-w sst turbulence model .I am getting area average weighted wall y+ as 27. Is this value acceptable? I've read from different sources that the y+ value should be less than or equal to 1.

Of course he is asking because he is in doubt . . . I am sure you have had some doubts along your career as well.. He read some stuff and now he needs to verify that information ![]() |

Just FYI a more through approach is to have the Y+ equal to 2 or 3 for coarser grids with 10-20 layers, then Y+ 1 for more refined grids with 20-30 layers and anything lower than Y+1 for even more refined grids with subsequently more layers.. |
