Hello!


I am currently trying to simulate laminar Mach 2 flow over a flat plate in Fluent. I am specifically trying to obtain qw values over the length of the plate, which seems easy enough to do using the XY plot. However, I'm getting what seems like terribly unrealistic values for qw, max around 1.9e8 W/m2 at the leading edge. I want to observe how the fluid transfers heat to the plate, but this seems quite high.


I am unable to find any issue with my boundary conditions (shown below) and I believe my mesh to be refined enough near the wall, though perhaps that may be the issue. Mass flow through the inlet/outlet and averaged enthalpy at the inlet have converged perfectly, with residuals past 1e-6. Has anyone experienced a similar problem where results seem accurate except seemingly for the heat transfer only? Any tips would be greatly appreciated, and if any other info is needed let me know.


Plate geometry and conditions are taken from CFD by Anderson, Chapter 10, save for changing M=4 to M=2
Inlet: Velocity inlet, uinf = Mach 2, Tinf = 288.16 K, P = 101325 Pa
Outlet: Pressure outlet, T = 288.16 K, P = 101325 Pa
Wall: No-slip, isothermal, Tw = 288.16 K
Farfield: Pressure farfield, uinf = Mach 2, Tinf = 288.16 K, P = 101325 Pa
