Abstract

The Study investigates the Dufour and Soret effect on the onset of thermosolutal instability in a rotating porous layer using Darcy’s law and Linear Stability analysis. When the rotation Lewis number, Solutal Rayleigh number Dufour parameter, and Soret parameter, are set equal to zero, It was observed that the principle of exchange of stabilities holds and hence found that instability manifested itself as stationary convection. Rotation and Dufour parameter respectively have a destabilizing effect on the system as the Rayleigh number, increases with an increase in Rotation and Dufour parameters for all values of the wave number and Solutal Rayleigh number while the Soret parameter has a stabilizing effect on the system as the Rayleigh number decreases with increase in Soret parameter

Keywords: Dufour, Soret, Thermosolutal, Porous layer,
