Iterative Adaption of the Bidimensional Wall of the French T2 Wind Tunnel around a C5 Axisymmetrical Model: Infinite Variation of the Mach Number at Zero Incidence and a Test at Increased Incidence

摘要

The top and bottom two-dimensional walls of the T2 wind tunnel are adapted through an iterative process. The adaptation calculation takes into account the flow three-dimensionally. This method makes it possible to start with any shape of walls. The tests were performed with a C5 axisymmetric model at ambient temperature. Comparisons are made with the results of a true three-dimensional adaptation.
