Vanishing of the dissipation term in Roe's scheme for a stationary shear wave
I have another doubt In Van Leers paper (AIAA 87-1104) comparing several different algorithms, he points out that the dissipation matrix of Roe's scheme vanishes when a single steady flow such as a shock, contact or a shear surface is aligned with the interface. How to prove that the dissipation term 1/2|Bbar(Qr,Ql)|deltaQ vanishes for a stationary shear (vorticity) whose wave front is parallel to the grid interface?
Kindly help me as to how prove it? This is also from one of my assignments. :confused::( !!
