This study investigates the unsteady flow of Al2O3-Cu/water hybrid nanofluid on a stagnation point of a permeable rigid surface. The similarity equations are obtained using similarity variables and then solved using the bvp4c solver. The outcomes show that dual solutions exist for the negative unsteadiness and some mass flux parameters. Besides, the heat transfer rate is intensified with the hybrid nanoparticles. Moreover, the increasing of the mass flux parameter tends to increase the heat transfer rate and the skin friction on the surface. Also, the reduction of the skin friction coefficient is observed, and a higher heat transfer rate is achieved for smaller values of the unsteadiness parameter. Finally, by a temporal stability analysis, it is found that the first solution is stable and reliable as time evolves.

可渗透刚性表面驻点上的非稳态混合纳米流体流动

本研究调查了 Al 2 O 3的非定常流动-Cu/水混合纳米流体在可渗透刚性表面的驻点上。使用相似变量获得相似方程,然后使用 bvp4c 求解器求解。结果表明,负不稳定和一些质量通量参数存在双重解。此外,混合纳米粒子的传热速率得到了增强。此外,质量通量参数的增加往往会增加传热速率和表面的皮肤摩擦。此外,观察到皮肤摩擦系数的降低,并且对于较小的不稳定参数值实现了较高的传热率。最后,通过时间稳定性分析,发现第一个解随着时间的发展是稳定可靠的。
