Emerging Technology for Transonic Wind-Tunnel-Wall Interference Assessment and Corrections

Experimental and numerical Investigation of wind tunnel wall interference near Mach one

“…This condition is practically impossible to achieve in an impervious-wall test section unless, of course, the walls can be shaped to resemble streamlines in unbounded flow< 7 >. The most effective reduction of x can be realised by venting air into the plenum, as described by Equation (8). If M 0 is sufficiently close to unity, the stream Mach number correction can be defined as…”
