Abstract This paper explores the Darcy-Forchheimer two-dimensional flow of nanofluid due to curved stretching sheet. Brownian motion and thermophoresis effects are taken in to account. Bejan number and entropy generation are analyzed in presence of MHD, convective boundary conditions, partial slip and viscous dissipation. Nonlinear ordinary differential systems are developed through transformations. Convergent series solutions are constructed by using NDSolve of MATHEMATICA. Behavior of involved variables on flow characteristics is shown through graphs. Velocity reduces for higher slip parameter and Forchheimer number. Temperature and concentration have direct relation with thermal and solutal Biot numbers. An increase in entropy generation is seen for higher curvature parameter, porosity parameter and Brinkman number. Decrease in Bejan number is observed for higher estimations of Brinkman number and slip parameter. Comparative study of present results with previous information in a limiting sense is made.

熵生成最小化：Darcy-Forchheimer 纳米流体流动由于弯曲拉伸片和部分滑移

摘要 本文研究了弯曲拉伸片引起的纳米流体的Darcy-Forchheimer二维流动。布朗运动和热泳效应被考虑在内。在存在 MHD、对流边界条件、部分滑移和粘性耗散的情况下分析 Bejan 数和熵生成。非线性普通微分系统是通过变换发展起来的。使用 MATHEMATICA 的 NDSolve 构造收敛级数解。相关变量对流动特性的行为通过图表显示。更高的滑移参数和 Forchheimer 数会降低速度。温度和浓度与热和溶质比奥数直接相关。对于更高的曲率参数、孔隙率参数和 Brinkman 数，可以看到熵产生的增加。对于 Brinkman 数和滑移参数的更高估计，观察到 Bejan 数的减少。在有限意义上对当前结果与先前信息进行比较研究。
