Linear Stability of Thermosolutal Convection in a Micropolar Fluid Saturating a Porous Medium
In the present paper, the theoretical investigation of the double-diffusive convection in a micropolar fluid layer heated and soluted from below saturating a porous medium is considered. For a flat fluid layer contained between two free boundaries, an exact solution is obtained. A linear stability analysis theory and normal mode analysis method have been used. For the case of stationary convect...
متن کاملThermal Convection of Rotating Micropolar Fluid in Hydromagnetics Saturating A Porous Medium
This paper deals with the theoretical investigation of the thermal instability of a thin layer of electrically conducting micropolar rotating fluid, heated from below in the presence of uniform vertical magnetic field in porous medium. A dispersion relation is obtained for a flat fluid layer, contained between two free boundaries using a linear stability analysis theory, and normal mode analysi...
متن کاملThermosolutal Convection of Micropolar Rotating Fluids Saturating a Porous Medium
Double-diffusive convection in a micropolar fluid layer heated and soluted from below in the presence of uniform rotation saturating a porous medium is theoretically investigated. An exact solution is obtained for a flat fluid layer contained between two free boundaries. To study the onset of convection, a linear stability analysis theory and normal mode analysis method have been used. For the ...
متن کاملWeakly non-linear magneto-convection in a viscoelastic fluid saturating a porous medium
In this paper the effect of magnetic field on linear and non-linear thermal instability in an anisotropic porous medium saturated with viscoelastic fluid is considered. Normal mode technique is used to investigate the linear stability analysis, while non-linear stability has been done using minimal representation of truncated Fourier series involving only two terms. Extended Darcy model, which ...
