Supersonic flow and shock wave
WebSupersonic Flow and Shock Waves. By R. Courant K. O. Friedrichs. (Pure and Applied Mathematics, a Series of Texts and Monographs, Vol 1.) Pp. xvi + 464. (New York and … WebNormal shock waves can be easily analysed in either of two reference frames: the standing normal shock and the moving shock. The flow before a normal shock wave must be supersonic, and the flow after a normal shock must be subsonic. The Rankine-Hugoniot equations are used to solve for the flow conditions.

In the left part of the region, the …
WebApr 11, 2024 · As the supersonic flow expands, the expansion fans continue to develop, and then, a weak reattached shock wave forms. The shock wave continues to reflect off the upper wall boundary layer, and then, the reflected shock wave interacts with the mixing layer (x/h = 2.87). In case 3, the expansion fans induced by the splitter plate are dramatically ... WebThe supersonic flow of a reactive gas mixture with Mach reflection of oblique shocks and pulsed energy supply at the Mach stem is considered within the framework of the Chapman–Jouguet theory. An approximate analytical model is proposed that quickly determines the shape and size of the shock-wave structure as well as the flow …
WebMay 13, 2024 · The Mach number and speed of the flow also decrease across a shock wave. If the shock wave is perpendicular to the flow direction it is called a normal shock. On … WebLift and Drag at Supersonic Speeds. Air acts much differently at supersonic speeds than it does at subsonic speeds. When an aircraft approaches the speed of sound, the airflow …
The abruptness of change in the features of the medium, that characterize shock waves, can be viewed as a phase transition: the pressure-time diagram of a supersonic object propagating shows how the transition induced by a shock wave is analogous to a dynamic phase transition. When an object (or disturbance) moves faster than the information can propag…
WebOverview. Supersonic flow over a diamond-shaped airfoil is one of the classic canonical cases for demonstrating the application of shock-expansion theory. As the supersonic flow moves over the airfoil, it encounters both oblique shock waves and expansion waves.
