Abstract:
ABSTRACT The Effects of Parabolic and Inverted parabolic Salinity gradients on the onset of Double Diffusive Marangoni Convection in a two-layer system, comprising an incompressible two component fluid saturated porous layer over which lies a layer of the same fluid in the microgravity condition, are investigated. The upper boundary of the fluid layer is free and the lower boundary of the porous layer is rigid and both the boundaries are insulating to heat and mass. At the interface, the velocity, shear stress, normal stress, heat, heat flux, mass and mass flux are assumed to be continuous conducive for Darcy-Brinkman model. The resulting Eigen value problem is solved exactly. The Thermal Marangoni numbers for linear, parabolic and inverted parabolic salinity profiles are obtained. The effects of different physical parameters on the onset of double diffusive Marangoni convection are investigated for above profiles in detail. Keywords: Double diffusive convection, Salinity gradients, Thermal Marangoni numbers, Darcy-Brinkman model
