Flow Past a Cylinder
In the below paper, GuangShan Jiang and ChiWang Shu give an example of ENO and WENO handing nonrectangular domain. i.e. flow past a cylinder.
`Efficient Implementation of Weighted ENO Schemes', J. Comput. Phys, 126, 202 (1996). The problem is initialized by a Mach 3 shock moving toward the cylinder from the left. But this paper doesn't give the state of the flow before the shock (\rho,u,v,p). I am trying to do this case now. If you can give me some suggestions or some references, I will appreciate very much.

If you know the state of the gas one side and you know the shock speed, you can calculate the state on the other side from the jump conditions
[F] = s[U] 
Re: Flow Past a Cylinder
Unfortunately, I don't know the state of the gas one side. That paper only says a Mach 3 shock moving from left to right.
