October 19, 2023, 13:09	If flying a supersonic tube, how to get rid of the flow through the inner duct	#1
kev11 New Member Kevin Join Date: Jul 2023 Posts: 12 Rep Power: 3	Hello, I am simulating supersonic flow of some vehicle in the shape of a tube, similar to a straw shape. The normal shock inside the tube (inner duct) creates flow spillage, which spills out in the front of the tube (inlet) and causes a huge increase in drag. I want to get rid of the flow through the duct to get rid of that shock, which therefore gets rid of the increase in drag. How should I go about this? New boundary conditions?
