摘要

热传播管理和热能保存是近代工业和热科学面临的主要挑战。针对不同体积分数的纳米粒子以增强传热效果的研究层出不穷。因此,关于二氧化钛 TiO2、圆柱形氧化镁 MgO 和板状铝 Al 纳米粒子在不同温度的普朗特尔-艾林热水基中的分散,以及力对流的研究报告还很有限。同时,这些纳米粒子的杂化作用是促进传热的重要材料,可提高工业产出和热工程装置。因此,我们针对双楔形拉伸片中的热流体流动建立了偏导数数学模型。通过相似变量获得了一个不变变换模型,并采用谱准线性化方案对模型进行求解。通过与现有结果的验证,用表格和图表对结果进行了论证和定量讨论。结果表明,在 200C 的低体积分数和高体积分数(0.1 和 0.8)条件下,不稳定的三元混合热梯度分别在 0.20 和 0.07 的速率下减小和增大。此外,随着诱导磁场的升高,传热也会增强。

Dynamics of tri-hybridized Prandtl-Eyring thermal water-based magneto-nanofuids flow over double stretched wedge sheets experiencing force convection

The management of thermal propagation and preservation of heat energy are major challenges facing the industry and thermal science in recent times. Various studies have arisen on nanoparticles of different volume fraction for an enhanced heat transfer. Thus, limited reports have been offered on the dispersion of titanium dioxide TiO2, cylindrical magnesium oxide MgO and platelet aluminum Al nanoparticles in Prandtl-Eyring thermal water-based at different temperature experiencing force convection. Meanwhile, these nanoparticles’ hybridization served has essential materials to boost heat transfer for an improved industrial output and thermal engineering device. Hence, a partial derivative mathematical model is developed for the considered thermal fluid flow in dual wedge stretching sheets. An invariant transformed model is obtained via similarity variables, and a spectral quasi-linearization scheme solves the model. The results in tables and graphs are justified by validating with the existing ones and quantitatively discussed. It is seen with 200C at low and high-volume fraction (0.1 and 0.8), the ternary hybridized thermal gradient for unsteadiness decreases at 0.20 rate and increases at 0.07 rate respectively. Also, the heat transfer is strengthened with a rising induced magnetic field.
