In this study, the thermal stability and inherent irreversibility analysis for combustible third-grade fluid through a non-Darcian porous medium is examined. The heated fluid flow is assumed to be flowing steadily through parallel Riga plates that are exposed to asymmetrical convective cooling. Neglecting the reactant consumption, the governing equations are formulated and converted to coupled nonlinear Boundary-value problem by dimensional analysis. The dimensionless equations are solved numerically by Shooting-Runge-Kutta method and validated with spectral collocation method. Graphical and tabular illustrations are provided with sufficient explanations for the velocity, temperature, entropy generation and irreversibility ratio profiles.
