Mach 10 Aerofoil

The Mach 10 airfoil simulation below illustrates the use of CONVERGE™ for external flow calculations. The simulation was performed by using a coarse grid initially and then turning on embedded refinement. The activation of refinement was done automatically while the simulation was running (i.e., the simulation does not need to be stopped and restarted with a new grid).

@12345garhard: As you increase the mach number the standing shock wave moves in closer to the vehicle... I would actually say the shock almost looks TOO far out to be that high of a mach number...

[12345garhard]

Plus, when you get to high mach numbers with these type of geometries you generally see reflective shockwaves as well. Finally, at Mach 10 you will need more than just the flow solvers because you are well in the hypersonic range where molecules start to dissociate and chemical reactions are taking place. I'm not trying to discourage you, just saying keep working on it and maybe work on something below Mach 5 so that you don't have to worry about aerothermal effects yet. Good Luck!!!

too thick to be a NACA 0012 but definitely something symmetric. This is not a mach 10 flow.  With that blunt airfoil the bow shock would be way out in front of the airfoil. My guess is that you were not using a compressible solver for this simulation. You need to know the physics of the problem so that you can give your results a quick "does this makes sense" check. In this case, no it does not.

That airfoil reminds me of the NACA 0012 type.

Did you use a solver that solves compressible liquids, because at mach 10 the air will definitely be compressed. And that wing look more like a mach 0.1 style. :-)

Nice mesh…

Gr8 job. The black color is not even on the scale! I wanted to see the pressure gradient
