Abstract
This investigation sketches the simultaneous action of g-jitter and internal heat source on Walter-B viscoelastic fluid in highly permeable porous media. The porous medium is considered highly permeable to resist the effect of Darcian force, which opposes the fluid flow. A series solution method is used to quantify the heat transport in the convective system. The system of governing equations has been simplified into an ordinary differential equation with time-dependent coefficients, known as the Ginzburg�Landau equation. The effect of dimensionless parameters Prandtl number, Darcy number, thermal Rayleigh number, and internal Rayleigh number on thermal instability is discussed through figures. We also observe that an increase in the elastic parameter increases the rate of heat transport for a short time period. � 2021 by Begell House, Inc.
