Abstract

This exploration aims to study the comparison of heat transfer capabilities of two nanofluid oblique, steady stagnation-point flow combinations comprising single-walled carbon/water (SWCNHs/water) and multiwalled carbon nanotube/water (MWCNTs/water) toward a stretching surface influenced by nonlinear thermal radiation employing the Xue model. This envisaged comparison model is inimitable and still scarce in the literature. Relying on the Tiwari–Das nanofluid model, a mathematical framework is constructed. The system of partial differential equations is converted using suitable transformations into an ordinary differential system of three equations, which is evaluated numerically using the bvp4c method. The physical behavior of significant parameters and their graphical representation are thoroughly examined. The results show that the SWCNHs/water nanofluid outperforms the MWCNTs/water nanofluid. It is further witnessed that SWCNH nanoparticle contained nanofluid has considerably greater thermal radiation than MWCNT nanoparticles. The envisaged model is also validated by comparing it with a published study.

考虑薛模型的纳米流体在斜滞点流动的热性能比较分析：太阳能应用

摘要

该探索旨在研究两种纳米流体倾斜、稳定驻点流动组合的传热能力比较，包括单壁碳/水 (SWCNHs/水) 和多壁碳纳米管/水 (MWCNTs/水) 对拉伸表面的影响通过采用 Xue 模型的非线性热辐射。这种设想的比较模型是无法模仿的，并且在文献中仍然很少见。依托Tiwari-Das纳米流体模型，构建了数学框架。使用适当的变换将偏微分方程系统转换为三个方程的常微分系统，使用 bvp4c 方法对其进行数值评估。对重要参数的物理行为及其图形表示进行了彻底检查。结果表明SWCNHs/水纳米流体优于MWCNTs/水纳米流体。进一步见证了含有 SWCNH 纳米粒子的纳米流体具有比 MWCNT 纳米粒子大得多的热辐射。设想的模型也通过将其与已发表的研究进行比较来验证。
