“…The analysis of the exponential kind of heat source on parabolic flow on non-Newtonian fluid was studied by Samrat et al [28]. For the composite layers, the doublecomponent convection with profiles and a heat source was studied by Manjunatha et al [29] and the triplecomponent convection with temperature gradients and a heat source was studied by Yellamma et al [30]. They obtained the Marangoni effects for a two-layer configuration.…”

The joint influences of variable heat source patterns and temperature-reliant viscosity on the onset of convective motion in porous beds in the presence of gravity variance have been investigated. The linear analysis is performed using normal mode analysis and the Galerkin technique is applied to analyze the impact of variable heating and changeable gravity field on the behavior of system stability. The exponential temperature-dependent viscosity is considered. We examined three different types of heat source and gravity variance function combinations:Convection is accelerated by increases in viscosity and the gravity variance parameter, but decelerated by increases in the heat source strength. It has been shown that the configuration is more stable when the gravity variance and heat source functions are combined in instance (ii), but less stable when they are combined in case (iii).

The investigation focuses on the consequences of various thermal distributions examined in the context of Magneto–Darcy–Rayleigh–Bénard (MDRB) convection onset under local thermal non-equilibrium (LTNE). The system under consideration consists of a two-layer configuration, with an incompressible fluid and horizontally positioned adiabatic peripheries. An analytical solution to the resultant problem is accomplished using the regular perturbation method. Concerning the six thermal distributions, we examine variables such as the ratio of heat expansion in the solid phase, the ratio of heat diffusivities in the solid phase, and the inter-phase heat diffusivity ratio, which exhibits a propensity towards LTNE. Furthermore, we investigate the consequences of modifying the values of constraints, namely, the ratio of heat expansion in the fluid phase, the ratio of heat diffusivities in the fluid phase, the porous parameter, the heat ratio, and the Chandrasekhar number. The empirical observations indicate that the model (iii) exhibits a significantly higher degree of instability when compared to other distributions. Conversely, model (v) demonstrates a notable level of stability. Moreover, it is intriguing that the system governed by the model (vi) exhibits higher stability than the model (iv) thermal distribution within the context of a composite system.
