Abstract The steady magnetohydrodynamic stagnation point flow and heat transfer over a stretching/shrinking surface in a hybrid nanofluid with partial slip and viscous dissipation were theoretically/numerically studied. The governing equations of the problem were turned into ODEs by using appropriate transformations. The plots of most important parameters were presented for both surfaces. It was found that on increasing the magnetic parameter, the hybrid nanofluid is better as a heater rather than nanofluid, however, it is better as a cooler on rising Eckert number, the stretching and slip parameters. For shrinking sheet, critical regions of unique/dual solution have been introduced. Further, stability of the unique/dual solution was studied where three regions of stability were noticed. It was deduced that the velocity and temperature are sensitively available close to the terminated line in the dual solution region. It was also proved that their behavior is absolutely different over the three regions of stability.

MHD 在具有部分滑移和粘性耗散的拉伸/收缩表面上接近停滞点的流动和热传递：混合纳米流体与纳米流体

摘要 从理论上/数值上研究了具有局部滑移和粘性耗散的混合纳米流体中拉伸/收缩表面上稳定的磁流体动力学驻点流动和热传递。通过使用适当的变换，问题的控制方程被转化为 ODE。给出了两个表面的最重要参数的图。结果表明，在增加磁参数时，混合纳米流体作为加热器比纳米流体更好，但是，随着埃克特数、拉伸和滑移参数的增加，混合纳米流体作为冷却器更好。对于收缩片材，引入了唯一/双重解决方案的关键区域。此外，研究了唯一/双重解决方案的稳定性，其中注意到三个稳定区域。推断出在双解区域中靠近终止线的速度和温度是敏感的。还证明了他们的行为在三个稳定区域上是完全不同的。
