Linear and Weakly Nonlinear Triple Diffusive Convection in a Couple Stress Fluid Layer [PDF]

, 2014
The effect of couple stresses on linear and weakly nonlinear stability of a triply diffusive fluid layer is investigated. Several departures not observed either in singly or doubly diffusive couple stress fluid layer have been identified while analyzing ...

Convection in Couple-Stress Magneto-Fluid

IOSR Journal of Mathematics, 2016
Double-diffusive convection in a couple-stress fluid in the presence of uniform vertical magnetic field through porous medium using linearized stability theory and normal mode analysis is studied. For the case of stationary convection, the stable solute gradient, magnetic field and couple-stress are found to have stabilizing effects whereas medium ...
