Spalart - Almaras Model - Inlet conditions.
 

HI,

I am using Spalart - Almaras model in Fluent to simulate hypersonic flows. I do not find much information about this particular turbulence model.

Does anybody know anything about the user inputs required here ? Especially, about the turbulence length scale ?

In case you need any additional info: The case is run at 8.6 Mach, as a 2D, unsteady and external flow.

Thanks in advance and waiting for your reply.
