Hypersonic Re-entry Simulation

alescala99 · July 21, 2021, 09:27

Good Afternoon to all,
I'm writing in this forum, because I need help for my project about a CFD simulation in Hypersonic Conditions (Mach Numbers up to 22). I would ask to you what is the best setup in Fluent to obtain a good convergence, because all I tried was useless and I controllled my mesh and It's pretty well done, but I on't know what's the best Setup. Thank you in advice to all of you for your answers.

start with small Mach numbers, get convergence and increase Mach number for next iteration

Okay, This is what I think about, but even starting from small Mach numbers I do not have convergence.. I suppose I'm making mistake in setup because It's my first Hypersonic simulation in Fluent, so that I would know what is the best setup I can use in this case (Mach Number = 19)
