Entropy optimized nanomaterial flow with Soret and Dufour impacts

Abstract

The considered configuration has relevance for polymer extrusion, cable coating, spinning of filaments and metallurgical processes. In view of such important applications the irreversibility analysis in hydromagnetic Maxwell nanoliquid flow by stretching cylinder is considered. Darcy-Forchheimer expression characterizes porous medium. Heat and mass transfer by convective conditions are studied. The aspects of random motion, thermophoresis and Soret and Dufour impacts are under consideration. Energy expression comprises thermal radiation, Dufour effect, random motion and thermophoresis. Entropy production for chemically reactive flow with Darcy-Forchheimer relation is studied. Nonlinear ordinary equations are obtained by employing adequate transformations. Numerical solutions are computed through ND-solve technique. The behaviors of emerging parameters for quantities of importance are explored. Clearly it is noticed that velocity tends to decrease as the material parameter increases whereas opposite behavior witnessed for mixed convection variable. Temperature distribution enhanced against Dufour and thermal Biot numbers. Concentration shows increasing behavior against solutal Biot and Soret numbers. Entropy rate shows increasing behavior against higher Brinkman number whereas opposite scenario noticed through Bejan number. An opposite behaviors for entropy and Bejan number against curvature variable are witnessed. Thermal distribution increased for higher Eckert number.
