Exergy Analysis for Combustible Third-Grade Fluid Flow through a Medium with Variable Electrical Conductivity and Porous Permeability

A mathematical investigation of a thermodynamical system linked with energy management and its impact on the environment, especially climate change, is presented in this study. In regard, numerical flow heat transfer hydromagnetic third-grade liquid through porous medium. The permeability medium electrical conductivity fluid are assumed to be temperature functions. appropriate formulations for momentum, energy, entropy equations both dimensional dimensionless forms. We obtained solutions using spectral version Chebyshev collocation method compared result shooting Runge–Kutta method. Numerical results velocity, temperature, entropy, Bejan profiles communicated tables graphs adequate physical interpretation. thermal stability thermo-fluid that guarantees prevention spontaneous heating fuels change also included analysis.
