摘要：

Entropy analysis for magnetohydrodynamic (MHD) unsteady flow of Prandtl fluid by a stretchable surface is addressed. Thermal transport with radiation, magnetic field and dissipation is taken. Physical behaviors of Soret and Dufour impacts are examined. Features of entropy have been deliberated. Mass transfer with first order chemical reaction is addressed. Dimensionless problems are simulated by finite difference method. Graphical illustrations show outcomes of fluid motion, thermal and mass transport and entropy. An intensification in Reynold number improves the velocity. Higher magnetic variable lead to enhance thermal field and entropy rate. Temperature enhancement is observed through radiation while reverse trend holds for Prandtl number. Higher Soret number rise the concentration while opposite holds for Schmidt number. Higher estimation of radiation lead to improve both entropy rate and thermal field. © 2022 Elsevier Ltd
