The enhancement of heat transfer is an important factor in heat exchangers, nuclear reactors, electric coolers and solar collectors. The enhance in rate of heat and mass transfer can be achieved by choosing suitable nanofluid or ferromagnetic fluid as an active liquid. In this connection, we have investigated the ferromagnetic nanofluid flow past a flat elastic sheet with porous medium and chemical reaction. Further, nanofluid is considered and simulated through the Koo and Kleinstreuer-Li (KKL) nanofluid model. The described governing equations are reduced to ordinary differential equations (ODE's) by means of apt similarity transformations and then they are numerically tackled using Runge Kutta Fehlberg-45 (RKF-45) scheme along with shooting method. The graphical results of the velocity, concentration and thermal profiles along with skin friction, Sherwood and Nusselt numbers are found to get an obvious insight of the existing boundary flow problem. The results reveal that, increasing values of ferromagnetic interaction parameter decays the velocity gradient but converse trend is depicted in thermal gradient due to the frictional heating between fluid layers. The increasing values of porosity parameter slowdowns the rate of heat transfer and velocity gradient.

考虑磁偶极子和化学反应的用于模拟纳米流体在拉伸片上流动的 KKL 相关性
传热的增强是热交换器、核反应堆、电冷却器和太阳能收集器中的一个重要因素。通过选择合适的纳米流体或铁磁流体作为活性液体，可以提高传热和传质速率。在这方面，我们研究了铁磁纳米流体流过具有多孔介质和化学反应的平坦弹性片。更远，通过 Koo 和 Kleinstreuer-Li (KKL) 纳米流体模型考虑和模拟纳米流体。通过适当的相似变换将所描述的控制方程简化为常微分方程 (ODE)，然后使用 Runge Kutta Fehlberg-45 (RKF-45) 方案和射击方法对它们进行数值处理。速度、浓度和热分布以及皮肤摩擦、舍伍德和努塞尔数的图形结果被发现可以明显地了解现有的边界流动问题。结果表明，铁磁相互作用参数值的增加会衰减速度梯度，但由于流体层之间的摩擦加热，热梯度呈现相反的趋势。
