Abstract
Two methods to experimentally investigate supersonic ground effect problems in a wind tunnel have been examined to determine their relative effectiveness compared to a more realistic, but physically unfeasible, representation of the ground effect by means of a moving ground. Experimental data were compared with the results of numerical simulations. The latter, once validated against pressure data from the wind tunnel, confirmed that generally a symmetry technique is more suitable than an elevated ground approach.
