A model development for thermal and solutal transport analysis in radiating entropy optimized and magnetized flow of nanomaterial by convectively heated stretched surface

Abstract

Entropy optimized characteristics for chemically reactive MHD flow by a convectively heated stretched wall is addressed. Constitutive relation for Reiner-Rivlin fluid in formulation is employed. Ohmic heating, dissipation and radiation in thermal relation are attended. Buongiorno model is incorporated to discuss the random and thermophoresis diffusions. Additionally homogeneous-heterogeneous reactions at surface are considered. Entropy rate is calculated. Non-dimensional differential systems are first obtained through suitable transformation and then numerically tackled by ND-solve method. Entropy rate, concentration, flow and temperature are organized. Nusselt number and coefficient of skin friction are explored. An improvement in magnetic field corresponds to reduce fluid flow while opposite behavior noted for skin friction coefficient. Larger estimation of fluid variable boosts up the velocity. Entropy rate and temperature for radiation are enhanced. Higher thermophoresis parameter leads to amplify the concentration and thermal field. Improvement in entropy rate and Nusselt number against radiation. Temperature for Eckert number is enhanced. Larger approximation of homogeneous reaction variable decay the concentration. An enhancement in entropy rate is seen through magnetic field. Larger approximation of magnetic parameter corresponds to augment heat transport rate. Nusselt number against thermal Biot number is enhanced.
