I want to solve a 2-dimension DC nozzle flow in fluent. I want to use komega SST turbulence model. I have some problems in meshing the nozzle. nozzle is designed for mach number of 2.
For kw-SST what is the better value of y+? What is the value of 1st raw thickness and number of layers? thank you. |

I love to set parameters as exponential law at nozzle-wall,
usually 0.001 mm, ratio of 1.2 is given for my simulation (that conditions well predict the boundary layer/flow separation around the wall) - sorry about my weird writes, I'm not good at English - |
