Stability Analysis of Thermosolutal Convection in a Horizontal Porous Layer Using a Thermal Non-equilibrium Model

摘要：

We use a linear stability analysis to investigate the onset of thermosolutal convection in ahorizontal porous layer subject to fixed temperatures and chemical equilibrium on the boundariessurfaces. The critical Rayleigh number and the corresponding wave number for the exchange of stabilityand overstability are obtained. The critical value of the parameters for oscillatory convection occurs areobmined．Besides,asymptotic analysis for both small and large values of inter-phase heat transfercoefficient H．
