In this article, we consider the low Mach number limit of the compressible nematic liquid crystal flows in a 3D bounded domain. We establish the uniform estimates with respect to the Mach number for the strong solutions with large initial data in a ...

Singularities in mass-loaded MHD flow: The cometary bow shock [PDF]
We present a one-dimensional model of the mass-loading of the solar wind by cometary ions which predicts a singularity in the mass-loaded flow at M = 2. Further, a subshock occurs when the flow speed reaches M almost-equal-to 1.15.

Morphology and Mach Number Dependence of Subsonic Bondi–Hoyle Accretion
We carry out three-dimensional computations of the accretion rate onto an object (of size R _sink and mass m ) as it moves through a uniform medium at a subsonic speed v _∞ . The object is treated as a fully absorbing boundary (e.g., a black hole).

The transition of the boundary layer is an important issue that must be considered in the design of hypersonic vehicles. During the ascent phase of the vehicle, both the Mach number and the flight altitude increase simultaneously and affect the location ...

Low Mach number equation sets approximate the equations of motion of a compressible fluid by filtering out the sound waves, which allows the system to evolve on the advective rather than the acoustic time scale.

Investigation of Rotor Tip Vortex in Hover Based on IDDES Methods
A calculation and analysis program of high-precision numerical simulation for rotor blade tip vortex in hovering state was developed. The fifth order Roe-WENO scheme was carried out in order to reduce the numerical dissipation of the rotor wake region ...

Whistler Critical Mach Number Concept Revisited
Low Mach number, fast magnetosonic,  dispersive shocks are formed if the characteristic scale of the shock front exceeds the characteristic the spatial scale associated with resistive processes. In these cases, dispersion arrests the nonlinear steepening of the shock front. According to the established view,  a whistler wave precursor,

To overcome the difficulty in the DNS of compressible turbulence at high turbulent Mach number, a new difference scheme called GVC8 is developed. We have succeeded in the direct numerical simulation of decaying compressible turbulence up to turbulent ...
