Comparison of experimental and theoretical boundary-layer separation for inlets at incidence angle at low-speed conditions [PDF]
Comparisons between experimental and theoretical Mach number distributions and separation locations are presented for the internal surfaces of four different subsonic inlet geometries with exit diameters of 13.97 centimeters.

, 2017 We perform global three-dimensional MHD simulations of unstratified accretion disks in cataclysmic variables (CVs). By including mass inflow via an accretion stream, we are able to evolve the disk to a steady state. We investigate the relative importance

Intergrain forces in low-Mach-number plasma wakes
Physical Review E, 2012 Large-scale particle-in-cell calculations of the plasma wake interactions of two negatively charged grains smaller than the Debye length are carried out using the COPTIC code over a wide range of subsonic plasma flow velocities. In plasmas with temperature ratio $T_e/T_i=100$, it is found that a single grain's oscillatory wake disappears for flow Mach ...

Absolute/convective instabilities and the convective Mach number in a compressible mixing layer [PDF]
Two aspects of the stability of a compressible mixing layer: Absolute/Convective instability and the convective Mach number were considered. It was shown that, for Mach numbers less than one, the compressible mixing layer is convectively unstable unless ...

Altitude performance of a low-noise-technology fan in a turbofan engine with and without a sound suppressing nacelle [PDF]
Test variables were inlet Reynolds number index (0.2 to 0.5), flight Mach number (0.2 to 0.8), and flow distortion (tip radial and combined circumferential - tip radial patterns). Results are limited to fan bypass and overall engine performance.
