WebDec 27, 2024 · The linear analysis enables to identify mechanisms and modes prevailing at the threshold of convective instability in a horizontal binary-mixture layer in accordance with values of control parameters like the Rayleigh number and the separation ratio (Platten and Legros 1984; Jiang et al. 1991; Platten 2006 ). WebApr 12, 2009 · The Darcy Model with the Boussinesq approximation is used to study natural convection in a shallow porous layer, with variable permeability, filled with a binary fluid. The permeability of the medium is assumed to vary exponentially with the depth of the layer. The two horizontal walls of the cavity are subject to constant fluxes of heat and solute … ea play hub xbox one
