Abstract:
Experimental data are presented for the development of compressible turbulent boundary layers moving from a solid onto a transpired surface, and vice versa. The data were obtained at free stream Mach numbers of 1.8 and 3.6 (Reynolds numbers per metre of 2.45 x 10power7 and 5.45 x 10power7 respectively) and transpiration rates up to 0.0044, for nominally zero heat-transfer conditions. The results are compared with theoretical predictions obtained from a method based on the eddy-viscosity concept. The work described in this report is based on experimental investigations conducted by the author while at Cambridge University Engineering Department, and presented in a Ph.D. dissertation (Marriott).
