airfoil
 

Can anyone please help me with deciding a proper domain size for an airfoil of unit chord length (NACA64 A010 for example)? the incoming flow is at three different speeds, M=0.8, M=1.08 & M=5. the airfoil is to meshed properly in order to capture the different types of shockwaves generated. it will be great if someone can provide me with some info on where i can find info on the domain size, position of shockwaves and the approx length of shockwaves (WRT chord length) will be greatly appreciated. Thanks in advance.
