Thermal instability of rotating Maxwell visco-elastic fluid with variable gravity in porous medium. (English) Zbl 1360.76343

Summary: The effect of variable gravity and rotation is investigated on the thermal instability of Maxwell visco-elastic fluid with variable gravity in porous medium. It is found that, in case of stationary convection, variable gravity has destabilizing effect while rotation has stabilizing effect on the system. Medium permeability has stabilizing/destabilizing effect on system depending upon certain condition. The mode may be non oscillatory or oscillatory.
