Studying entropy generation allows scientists and engineers to optimize processes, design more efficient systems, and develop sustainable technologies. These studies aim towards minimizing energy losses, reducing environmental impacts, and advancing the frontiers of thermodynamics and energy science. As such, the current investigation expunges the dynamics of heat, flow, entropy and irreversibility analysis for a magnetized and dissipative Carreau fluid flow over a nonlinearly stretching sheet. The model is subject to thermal and electrical conductivity variations, higher-order adherence factors and nonlinear convective motion over an inclined nonlinear surface. Herein, the heat source in the flow system is considered space and temperature-dependent. The mathematical model presented in PDE systems is transformed to ODEs via similarity transformation. Numerically, the solutions to the distribution profiles are approximated via Chebyshev Collocation Method (CCM) with the pseudospectra (differentiation matrix) technique. In the limited case, the results here benchmark existing literature. Our findings identified that thermal irreversibility dominated the entire flow system, further entropy generation and irreversibility enhancement requires more thermal energy. We as well elucidate that alteration of both heat source modulation affects the heat transfer coefficient while Joule heating effect generates inner energy which induces the Carreau fluid energy.
