Linear theory of particulate Rayleigh-Bénard instability
Suryansh Prakhar, Andréa Prosperetti
Abstract
Particles falling uniformly through a Rayleigh-B\'enard cell have a profound influence on the stability of the system. Mechanically, they exert a stabilizing effect akin to that of the solid phase in a porous medium. Their temperature, however, can markedly affect the undisturbed temperature distribution of the fluid phase with unexpected effects on the stability threshold.
