Detonation Wave Mach Number Dependence in a High Mach Number Flows [PDF]
22nd AIAA International Space Planes and Hypersonics Systems and Technologies Conference, 2018 The paper presents a study of detonation propagation in supersonic crossflows over a range of Mach numbers. The work is focused on characterizing the detonation wave dependence on the supersonic cross-stream Mach number. A high-enthalpy combustor is used to provide continuous premixed supersonic crossflows that interact with an orthogonal detonation ...

Mach number and temperature effects on jets [PDF]
11th Fluid and PlasmaDynamics Conference, 1978 M were carried out in a round jet over a range of exit Mach numbers from 0.3 to 1.7 and exit-toambient temperature ratios of 0.8 to 2.3 using a laser velocimeter. Mean velocities and turbulence intensities were measured and their distributions in the radial and axial directions were obtained.

The Speed of Sound and Mach Number Effects
The Journal of the Royal Aeronautical Society, 1963In most aerodynamic problems the speed of sound, a, is naturally taken as or where p, ρ and T are static values, γ is the specific heat ratio and R is the gas constant. This particular speed, however, is specifically that of plane waves advancing uniformly into an infinite expanse of a homogeneous medium.

The Speed of Sound and Mach Number Effects [PDF]
The Journal of the Royal Aeronautical Society, 1964 In a recent paper the suggestion is made that “it would be sensible when discussing the flow to use a Mach number based on the actual propagation velocity in the given circumstances.”This directs attention to the deeper question of whether or not a Mach number however defined is a rational parameter in terms of which to express effects of flow.In ...

Electron Heating in Superhigh Mach Number Shocks [PDF]
Astrophysics and Space Science, 1988 Fluid and MHD models, as well as direct extrapolation of the Earth’s bow shock measurements in the high Mach number (HMN) range (3 ≤ M F ≤ 12) to the superhigh Mach number (SHMN) range (M F > 30–40) predict that the downstream electron pressure p e2 is only a negligible fraction of the Rankine-Hugoniot downstream pressure p 2, i.e., P e2/p 2 ≈ M F 2 ...

Low Mach Number Limit on Exterior Domains
Acta Mathematica Scientia, 2012This paper is concerned with the low Mach number limit for the compressible Navier-Stokes equations in an exterior domain. We present here an approach based on Strichartz estimate defined on a non trapping exterior domain and we will be able to show the compactness and strong convergence of the velocity vector field.

Multibody interference at transonic Mach numbers
30th Aerospace Sciences Meeting and Exhibit, 1992An experimental and computational study has been made of the forces and moments on multibody configurations at Mach numbers from 0.6 to 1.2. The interference forces and moments that occur on symmetric double and triple body configurations at zero angle of attack are examined in detail.
