Computational Parametric Study of Sidewall-Compression Scramjet Inlet Performance at Mach 10
A computational parametric study of three-dimensional, sidewallcompression scramjet inlets was performed to identify the e ects of geometric parameters on inlet performance. The parameters were the leadingedge sweep angle, varied between 30 and 60 , and the leading-edge position of the cowl, located at the throat and at two forward positions. A laminar boundary layer with cold-wall (T wall = 30...
متن کاملReynolds Number and Cowl Position Effects for a Generic Sidewall Compression Scramjet Inlet at Mach 10: a Computational and Experimental Investigation
Reynolds number and cowl position effects on the internal shock structure and the resulting performance of a generic three-dimensional sidewall compression scramjet inlet with a leading edge sweep of 45 degrees at Mach 10 have been examined both computationally and experimentally. Prior to the experiment, a threedimensional Navier-Stokes code was adapted to perform preliminary parametric studie...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
15 صفحه اولon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
An Experimental Parametric Study of Geometric, Reynolds Number, and Ratio of Specific Heats Effects in Three-dimensional Sidewall Compression Scramjet Inlets at Mach
Since mission profiles for airbreathing hypersonic vehicles such as the National Aero-Space Plane include single-stage-to-orbit requirements, real gas effects may become important with respect to engine performance. The effects of the decrease in the ratio of specific heats have been investigated in generic three-dimensional sidewall compression scramjet inlets with leading-edge sweep angles of...
