Abstract
This paper addresses the mixed convective flow and heat transfer in combustible thirdgrade fluids through a slant porous channel filled with permeable materials. The fluid layer in contact
with the channel wall is exposed to asymmetrical slippage and isothermal conditions. We employ the
spectral Chebyshev collocation method (SCCM) to the coupled nonlinear flow governing equations
and validate using the Shooting–Runge–Kutta method (RK4). Fluid velocity and temperature profiles,
local entropy generation, and irreversibility ratio are computed and analyzed quantitatively and
qualitatively. The convergence of the numerical method was demonstrated. The flow and thermal
effects results, entropy generation rate, and Bejan number revealed fascinating manifestations that
have profound implications in the design of thermo-mechanical systems. In particular, the thermal
analysis results are pertinent to optimal system designs that achieve efficient energy utilization.
