hey, i have a C-D nozzle and for meshing I am confused that to calculate from y+ calculator , i don't have values of velocity, boundary layer length all these values. what value should we use to get my y+ because the papers I am referring i am not getting it.

Please start a new thread for a new question. Do not hijack other threads. I have moved this question to a new thread.

You can estimate the y+ based on the centreline velocity you expect and the length of the C-D nozzle. It is just an estimate, you do not need to be precise here. Once you have a simulation result you can then establish whether it is adequate and you need to go finer or coarser.

Hey, can some help me to find the value of Y+ values through calculator wher i am not getting what value should i put for velocity, density, dynamic viscosity, length. As i am doing meshing for SSME CD nozzle. And if anyone know what is the inlet temperature of Space shuttle main engine?
