Abstract

In this study, double-diffusive natural convection in a Maxwell fluid saturated porous layer with internal heat under local thermal non-equilibrium model (LTNM) is studied analytically. The study has been carried out based on using linear stability analysis. The linear stability analysis is based on normal mode technique. The modified Darcy model for the viscoelastic fluid of the Maxwell type is used to govern the momentum equation. A two-field model for energy equation has been applied for fluid and solid phases. The onset criterion for stationary convection has been derived analytically. The effects of inter-phase heat transfer coefficient and internal heat parameter on the stability of the system are investigated.
