A learning about AUSM
 

Hi, everyone!

There is a problem when I using the AUSM scheme in NS-FVM solver.

Near the solid boundary, there is only pressure and viscous ones, so the flux of the nearest cell is always wrong.

The plus of three sides of the cell is much larger than the pressure and viscous.

I am very confused by this problem.

Can anyone help me to explain about it?

Thanks very much!
