This research work explores the effect of hybrid nanoparticles on the flow over a rotating disk by using an activation energy model. Here, we considered molybdenum disulfide and ferro sulfate as nanoparticles suspended in base fluid water. The magnetic field is pragmatic normal to the hybrid nanofluid flow direction. The derived nonlinear ordinary differential equations are non-dimensionalized and worked out numerically with the help of Maple software by the RKF-45 method. The scientific results for a non-dimensionalized equation are presented for both nanoparticle and hybrid nanoparticle case. Accoutrements of various predominant restrictions on flow and thermal fields are scanned. Computation estimation for friction factor, local Nusselt number and Sherwood number are also executed. Results reveal that the reduction of the heat transfer rate is greater in hybrid nanoparticles when compared to nanoparticles for increasing values of Eckert Number and the thermal field enhances for the enhanced values of volume fraction.

这项研究工作通过使用活化能模型探索混合纳米颗粒对旋转圆盘上的流动的影响。在这里，我们将二硫化钼和硫酸铁视为悬浮在基础流体水中的纳米颗粒。磁场垂直于混合纳米流体的流动方向是实用的。导出的非线性常微分方程是无量纲的，并借助Maple软件通过RKF-45方法进行了数值计算。对于纳米粒子和杂化纳米粒子的情况，都给出了无量纲方程的科学结果。对流场和热场的各种主要限制条件进行扫描。还进行了摩擦因数，局部努塞尔特数和舍伍德数的计算估计。
