WebDarcy–Bénard convection was studied by Banu & Rees (Reference Banu and Rees 2002) and Postelnicu & Rees (Reference Postelnicu and Rees 2003) for the case when the thermal equilibrium between the skeleton of the porous medium and the fluid breaks down, and these two solid and fluid phases have different temperatures. Using a two … WebJan 15, 2010 · In this paper there is studied the effect of a horizontal pressure gradient on the onset of Darcy–Bénard convection in a fluid-saturated porous layer heated from below, when the fluid and solid phases are not in local equilibrium. In the context of a linearized stability analysis, the problem is transformed into an eigenvalue equation. the krill orville
Darcy-Benard Marangoni Convection in a Composite Layer …
WebThe stability theory for Darcy–Benard convection in a porous layer heated uniformly from below was developed by Horton and Rogers,1 later confirmed independently by … WebThe onset of coupled Darcy-Benard-Marangoni convection in a liquid saturated porous layer of high permeability of practical importance is investigated by employing the … WebAug 21, 2024 · ABSTRACT. The present paper is the first to consider Darcy–Bénard–Bingham convection. A Bingham fluid saturates a horizontal porous layer that is subjected to heating from below. It is shown that this simple extension to the classical Darcy–Bénard problem is linearly stable to small-amplitude disturbances but … the kriging method
