In this paper, we discuss a two-dimensional numerical study of isothermal high Mach number Bondi– Hoyle–Lyttleton flow around a small accretor. The flow is found to be unstable at high Mach numbers, with the instability appearing even for a larger accretor. The instability appears to be the unstable radial mode of the accretion column predicted by earlier analytic work.
Granular matter consists of a large number of macroscopic particles; the thermal noise has no effect on the particle motion and the interactions are dissipative. These features make the granular flow very different from molecular fluids. One of the simplest situations to see the complex behavior of granular flow is the gravitational granular flow on a slope. When the inclination angle is small ...
Thermal management has become a critical issue for high heat flux electronics and energy systems. Integrated two-phase microchannel liquid-cooling technology has been envisioned as a promising solution, but with great challenges in flow instability. In this work, silicon nanowires were synthesized in situ in parallel silicon microchannel arrays for the first time to suppress the flow instabilit...
