hello everyone

Im working on a CFD analysis of a cone cylinder at different angles of attack. For my current analysis,….. Mach = 2.5, Re = 1.2 million, base diameter is 3.7inches.

The problem is that, Fluent can take Mach no.'s input but doesn't take Reynolds number's input. Instead, it requires operating pressure and temperature inputs. Since I don't know these values for my analysis, I have used many combinations of temperature, pressure and density values that will give me the same Reynold i.e (1.2 million) & Mach no. 2.5.

Solving in this way, I did not get the same results as wind tunnel's. My solution is grid independent. Was I doing it right? Or plz guide me, how should I solve the problem?

Regards.
