The result of this injection or suction of fluid is to modify the velocity and temperature distributions through the boundary layer so that the drag and the heat transfer are either reduced or increased. Most of the studies on this topic, however, deal with incompressible flow. The majority of the results on supersonic flow comes from the work of Squire and his students at Cambridge University [l-S]. These results are given for Mach mtmbers up to 3.6 at various injection rates. Full tables of measured profiles are presented and expressions for the law of the wall and the law of wake are proposed. As for the incompressible case, the law of the wall is obtained by straightforward application of the mixing-length theory [l]. Unfortunately, in those works the skin-friction coefficients are evaluated by means of the momentum-integral equation which tends to be very inaccurate, thus definitive checks on the proposed law of the wall are impossible. In a previous paper [6], the present author has proposed a skin-friction equation for transpired incompressible turbulent boundary layers. This equation is much less sensitive than the momentum-integral equation to small variations in the flow parameters so providing much more reliable results. The aim of this work is to extend this skin-friction equation to compressible flow.Submitted by Jairo Amaro (jairo.amaro@sibi.ufrj.br) on 2019-08-05T13:27:03Z No. of bitstreams: 1 1988_FREIRE_IJHMT31b-min.pdf: 248036 bytes, checksum: 5e71c1609a2b051473a3b6eeb9d565c1 (MD5)Made available in DSpace on 2019-08-05T13:27:03Z (GMT).
