Abstract
Magnetohydrodynamic Darcy-Forchheimer nanoliquid flow with entropy generation subject to stretched sheet is explored. Thermal expression with ohmic heating, dissipation and radiation is taken. In addition, random and thermophoresis motion impacts are considered. Soret and Dufour effects are addressed. Physical features of the entropy rate are analyzed. Entropy generation rate is used to amplify thermodynamical system performances. Nonlinear dimensionless systems are developed through the implementation of non-similarity transformations. The nonlinear resultant systems are numerically solved by local non-similarity via numerical scheme (ND-solve method). Physical description of various flow variables on velocity field, temperature distribution, entropy rate, concentration and Bejan number is scrutinized. Behaviors of different sundry parameters for Nusselt number and solutal transport have been discussed. For larger magnetic variable the velocity decays. A reduction is seen in temperature for Prandtl number. Higher porosity variable declines the velocity. An augmentation in temperature is improved for Dufour number. Similar trend of temperature through random and thermophoresis parameters is seen. Reverse effect of velocity is seen in concentration for Soret and Schmidt numbers. An improvement in concentration is noticed for the thermophoresis parameter. A reverse trend is noted for entropy rate versus radiation and Brinkman number.
