ABSTRACT

The effect of g-jitter on the buoyancy-driven convection in a binary viscoelastic fluid-saturated porous layer was studied using linear stability analysis. The Rivlin-Ericksen model was employed to characterize the viscoelasticity of the fluid, whereas the porous domain is considered to lack the local thermal equilibrium. The governing equations were converted into a system of ordinary differential equations using the Galerkin method. The stability of the system was investigated using Floquet's analysis and the obtained stability results are presented in detail. It was found that g-jitter has a significant effect on the onset of thermosolutal natural convection.
