Convection in a Maxwellian Viscoelastic Fluid Layer Through Porous Medium
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 8
Abstract
The triply-diffusive convection in a Maxwellian viscoelastic fluid layer is mathematically investigated through porous medium. Following the linearized stability theory and normal mode analysis, the dispersion relation is obtained. For the case of stationary convection, the solute gradients play stabilizing role in the system while medium permeability plays destabilizing role. The dispersion relation is also analyzed numerically. Further, the solute gradients are found to introduce oscillatory modes, which were non-existent in their absence. The sufficient conditions for the non-existence of overstability are also obtained.
