Effects of Thermal Nonequilibrium and Vertical Throughflow on the Onset of Forchheimer-Bénard Convection
A L Mamatha
The influence of vertical throughflow on thermal convection in a horizontal porous layer using a regime of local thermal nonequilibrium (LTNE) is investigated. The flow in the porous medium is governed by the Forchheimer equation and two energy balance equations, one for the solid phase and another for the fluid phase are used. The eigenvalue problem is solved numerically using shooting method combined with Runge-Kuatta-Fehlberg technique. It is noted that throughflow has a stabilizing effect on the stability of the system have the effect of delaying the onset of convection and reducing the size of convection cells. In addition, the influence of parameters representing the thermal non-equilibrium effects on convective instability is discussed in detail.
Keywords- Throughflow, porous layer, thermal non-equilibrium model, shooting method
