Entropy optimized radiative flow of viscous nanomaterial subject to induced magnetic field

Abstract

Here we examine the time-dependent viscous nanofluid flow with induced magnetic field. Energy expression comprising dissipation and radiation is accounted. Additionally Brownian movement and thermophoresis have been addressed. Thermal expression examines the thermodynamical system performance. Flow subject to first order reaction is chemically reactive. Dimensionless system is obtained through adequate variables. Dimensionless differential systems are solved employing finite difference scheme. Variations in velocity, induced magnetic field, thermal field and concentration against influential parameters are explored. Entropy generation is designed. Computational results of drag force, thermal transport rate and Sherwood number have been organized. Decay in velocity is seen for suction variable. Larger magnetic Prandtl number rises the thermal field. An increment in induced magnetic field is noticed through magnetic Prandtl number. Reverse results of entropy and thermal field for radiation are observed. Larger approximation of thermophoresis variable has reverse impact on concentration and thermal field. Higher estimation of Brinkman number correspond to an increase of entropy rate.
