The magnetohydrodynamic hybrid second-grade nanofluid flow towards a stretching/shrinking sheet with thermal radiation is inspected in current work. Main concern of current investigation is to consider hybrid [Formula: see text] nanofluid which is perceived by hanging two dissimilar kinds of nanoparticles known as alumina and copper within the base fluid. The fluid motion is produced by non-linear stretching/shrinking sheet. The modeled equations which comprise of energy, motion and continuity equations are changed into dimensionless form using group of similar variables. To determine the solution of transformed problem, the Homotopy Analysis technique is used. The findings of this work revealed that the magnetic parameter improves the heat transfer rate. This work also ensures that there are non-unique solutions of modeled problem for shrinking case and a unique solution for stretching case. Higher values of [Formula: see text] results in declining of flow field. Rise in [Formula: see text] agrees to a decline in velocity distributions. Higher values of second order fluid parameter reduces the viscosity of fluid and accordingly velocity increases. Velocity profile is also a decreasing function of volume friction.
在当前工作中，研究了磁流体动力学混合二级纳米流体流向具有热辐射的拉伸/收缩薄板的情况。当前研究的主要关注点是考虑混合的[公式：见文本]纳米流体，它是通过将两种不同类型的纳米颗粒（即氧化铝和铜）悬浮在基液中得到的。流体运动由非线性拉伸/收缩薄板产生。利用相似变量组将由能量、运动和连续性方程组成的建模方程转化为无量纲形式。为了确定转化问题的解，使用了同伦分析技术。这项工作的结果表明，磁参数提高了传热速率。这项工作还确保了对于收缩情况，建模问题存在非唯一解，而对于拉伸情况存在唯一解。[公式：见文本]的较高值导致流场下降。[公式：见文本]的增加与速度分布的下降一致。二阶流体参数的较高值降低了流体的粘度，因此速度增加。速度分布也是体积摩擦的递减函数。
