I am simulating a nozzle with a throat Re of 3500. I have the resources to directly resolve the jet breakdown after the nozzle but I need fluctuating inflow BCs to get physically realistic results.
I know there are fluctuating inflow BCs for LES but can't figure out how to use fluctuating inflow BCs when directly solving navier-stokes.
Using the built-in turbulence generation features from LES would be nice as otherwise I need to write my own udf.
If anyone has suggestions I'd appreciate it.
Thanks in advance.
