Using shock-expansion cancellation technique flow in the diverging part of a supersonic nozzle is brought back to free stream direction ( direction parallel to the axis of nozzle) where a rhombus shaped region(Test Section) is formed in which uniform flow is ensured. Refer Method Of Characteristics from Rathakrishnan For Diagram.
There is usually an additional throat placed in the tunnel downstream of the test section to shock down the supersonic flow to subsonic. The advantage of a supersonic continuous flow wind tunnel is the longer run times relative to a blowdown tunnel. The major disadvantage is the increased size and operating costs.

Goldenrod's Tunnel
Go to the Underground Tunnel in Goldenrod City. There is a Team Rocket Grunt there who will give you a uniform.
after you get 7 badges, head down to the goldenrod tunnel. talk to everyone it the tunnel. one of them will give you the uniform but you'll lose it as you proceed the storyline
