Low-Mach-number turbulence in interstellar gas revealed by radio polarization gradients
, 2011 The interstellar medium of the Milky Way is multiphase1, magnetized2 and turbulent3. Turbulence in the interstellar medium produces a global cascade of random gas motions, spanning scales ranging from 100 parsecs to 1,000 kilometres (ref. 4). Fundamental

Shock wave enhanced turbulent mixing in a wide-speed-range strut-based scramjet combustor
Propulsion and EnergyThe efficient mixing of fuel and oxidizer in a scramjet combustor is a critical issue for achieving future wide-speed-range flight. A numerical study is conducted using Reynolds-averaged Navier–Stokes equations coupled with shear stress transport k-ω ...

Courant Number and Mach Number Insensitive CE/SE Euler Solvers [PDF]
, 2005 It has been known that the space-time CE/SE method can be used to obtain ID, 2D, and 3D steady and unsteady flow solutions with Mach numbers ranging from 0.0028 to 10. However, it is also known that a CE/SE solution may become overly dissipative when the

MATHEMATICAL MODEL OF THE TSAGI’S TRANSONIC WIND TUNNEL T-106 AS A MACH NUMBER CONTROL OBJECT
Научный вестник МГТУ ГА, 2016 In this paper we propose a method of constructing a mathematical model of the TsAGI’s compressor transonic wind tunnel T-106 as a Mach number control object.

The low Mach number approximation, a soundproof approximation for ideal gases, is reconstructed in a manner not specific to ideal gases; its energetics is examined on the basis of this reconstruction. Consequently, it is shown that the conservation law of energy is not satisfied under the approximation; this implies that it excludes sound waves at the ...

Parallel flows as a key component to interpret Super-X divertor experiments
Nuclear FusionThe Super-X Divertor (SXD) is an alternative divertor configuration leveraging total flux expansion at the Outer Strike Point (OSP). While the extended 2-Point Model (2PM) predicts facilitated detachment access and control in the SXD configuration, these
