“…Suma et al [17] and Gangadharaiah et al [18] examined the joint impact of the internal heating and gravity variance on the device stability using the perturbation technique. Regardless, nonlinear gravity field variety with profundity can happen in sedimentary bowls, orogenic and epeirogenic developments of the crustal designs and Earth's outside (Shi et al [19], Nagarathnamma et al [20], Kiran et al [21], and Ananda et al [22]). The ferrofluid saturated porous layer convection problem is investigated in the changeable gravitational field by Mahajan and Parashar [23].…”

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).
