Abstract:

A wall adaptation strategy is put forward to test three dimensional models at transonic speeds in two dimensional adaptive wall wind tunnels. The departure effect of the aerodynamic walls from straight contour is evaluated by solving interference potential equation with FFT method and Wedemeyer theory is utilized for wall adjustment computation. Verification tests at high transonic Mach numbers show that the strategy is applicable to transonic adaptive wall wind tunnel testing.

Key words: wind tunnel testing, transonic flow, wallinter ference, a daptive wall wind tunnel
