Abstract

The e exible wall contour of the new adaptive wall test section is represented as a combination of base streamlines. The combination coefe cients are optimized to minimize the wall interference that is taken as the summation of the area weighted surface pressure difference between the free air and test section results. The numerical simulations show that the new adaptive wall test section produces similar results to the free air results. This new algorithm is free from the dee ciencies of conventional algorithms such as the dependence on a target line, a pressure hole distribution, and ine uence coefe cients. This new adaptation algorithm may be applied to real tests in which conventional adaptation algorithms fail.
