摘要

在工业应用中,尤其是在核冷却系统和核反应堆中,含有纳米颗粒的流体对提高能源性能至关重要。为此,我们提出了一种通过拉伸表面的三混合埃利斯旋转纳米流体,以增加热量的输送。通过悬浮三种不同类型的纳米颗粒,三混合纳米流体与基液形成了不同的化学和物理联系。在这篇文章中,纳米颗粒、和被混合在(水)中。这种混合物有助于降解有毒物质、清洁环境和许多其他需要冷却效果的设备。此外,还考虑了线性热辐射。流量和流体温度的控制方程最小化为常微分方程,这些方程采用 Runge Kutta 四阶 (RK45) 方法求解。通过图表对近似结果进行了分析,结果表明,与混合纳米流体和单一纳米流体相比,三混合纳米流体的热导率更有价值。磁参数和旋转参数值越高,流体温度越高,而埃利斯参数和热分层参数则呈相反趋势。此外,研究结果与之前的文献进行了比较,发现两者非常吻合。

Significance of tri‐hybrid nanoparticles on the dynamics of Ellis rotating nanofluid with thermal stratification
The fluids flow containing nano size particles is essential in industrial applications, especially in nuclear cooling system and nuclear reactor to increase the energy performance. In connection to this, a trihybrid Ellis rotating nanofluid flow through a stretching surface for increasing the heat transportation is presented. By suspending three different types of nano size particles the trihybrid nanofluid is formed with distinct chemical and physical connection into base liquid. In this article, the nano size particles , and are mixed in (water). This type of mixture helps in degradation of noxious substances, cleaning environmental and many other appliances that requires the cooling effect. In addition, the linear thermal radiation is also considered. The governing equations of the flow and fluid temperature are minimized to ordinary differential equations and these equations are solved by Runge Kutta order fourth (RK45) approach. The approximate results are analyzed via graphs and the results reveal that thermal conductivity of trihybrid nano type fluid is more valuable as compared to hybrid and single nanofluid. Higher values of magnetic and rotational parameter have aggrandized the fluid temperature and opposite trend has observed for Ellis and thermal stratification parameter. Moreover, the results are compared with previous literature and found an excellent agreement.
