Supersonic Flow Over Axisymmetric Cavities
37th AIAA Fluid Dynamics Conference and Exhibit, 2007Laminar and turbulent computations of rectangular cavities in Mach 2.2 flow are presented. Unsteady open cavities are shown in all laminar cases (L/D = 1.33, 10.33, 11.33 and 12.33) whilst turbulent simulations exhibit closed cavity flows for L/D of 11.33 and 12.33. The turbulent computations are supported by experimental schlieren images using a spark

For a definite Mach number, given by M2 = 4/(3−γ), all Mach lines in a steady plane two-dimensional potential flow of a perfect gas with expansion exponent γ have zero curvature. The use and significance of this relation are discussed, and the hypothetical expansion law consistent with straight Mach lines is deduced.

Supersonic viscous corner flows
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2011Results of numerical and experimental investigations of steady state supersonic viscous corner flows in simplified geometries that resemble typical wing body–fuselage intersections are presented. These flows are numerically calculated using the computational fluid dynamics code of Fluent and include the use of standard turbulence models.

Flow Dominating Instability in Supersonic Flows
2020The shock-induced separation is a common phenomenon in supersonic combustion, especially when the scramjet combustor works under high equivalence ratios. The low-speed recirculation zone and strong heat release enable the separated region to be an ideal place for flame stabilization.

Supersonic flows over cavities
Frontiers of Energy and Power Engineering in China, 2008The characteristics of supersonic cold flows over cavities were investigated experimentally and numerically, and the effects of cavities of different sizes on supersonic flow field were analyzed. The results indicate that the ratio of length to depth L/D within the range of 5–9 has little relevance to integral structures of cavity flow. The bevel angle

Combustion, Explosion, and Shock Waves, 1988
Examples of numeric modeling of complex combustion processes in supersonic flows are presented which illustrate the possibility of obtaining useful information which may reveal their basic regularities determined by the parameters of the entrance streams, mode of injection, type of fuel, and the interaction of various factors pertaining to combustion ...

This thesis is a presentation of the methods and concepts of the theory of linearized supersonic flow. The fundamental theory which serves as a basis for this investigation is discussed in the first two chapters. Special emphasis is placed upon the study of planar systems. A system of conical coordinates is introduced in which the method of separation

Turbulent supersonic channel flow
Journal of Turbulence, 2001The effects of compressibility are studied in low Reynolds number turbulent supersonic channel flow via a direct numerical simulation. A pressure-velocity-entropy formulation of the compressible Navier-Stokes equations which is cast in a characteristic, non-conservative form and allows one to specify exact wall boundary conditions, consistent with the ...

Supersonic Flow Past Airfoil Tips
Journal of Applied Mechanics, 1949Abstract Airfoils examined in this paper are constituted by developable surfaces with arbitrary cross sections, all the generators of the surfaces, including the sharp leading and trailing edges, being supersonic. The tips are constituted by supersonic sections, which are generally blunt.
