摘要

在这项创新性研究中,采用了一种独特的方法来模拟纳米流体在具有均匀流量表面的水箱内的流动特性。这项研究的测试流体是通过在水中加入不同形状的氧化铝粉末制作而成的。最终方程的推导涉及达西定律的应用和流函数的制定。容器受到洛伦兹力和重力的共同作用。添加添加剂后,努塞尔特数(Nu)显著增加,根据哈特曼数(Ha)的大小,分别增加了 19.8% 和 40.28%。此外,形状系数的增加也使 Nu 明显增加了 14%。值得注意的是,随着哈特曼数的增加,冷却率大幅降低了 51.33%。此外,在没有 Ha 的情况下,雷利数(Ra)的增加会导致 Nu 激增 65.8%。这项研究具有极其重要的意义,因为它引入了一种模拟正弦表面纳米流体流动的新技术,为了解容器内各种力的复杂相互作用提供了宝贵的见解。利用不同形状的氧化铝粉末为实验增添了一层复杂性,使这项研究对现有知识体系做出了值得注意的贡献。研究结果不仅加深了我们对传热动力学的理解,还为纳米流体在表面受热流影响不均匀的容器中的应用提供了实际意义。

Modeling of nanofluid thermophysical treatment through a permeable container under the impact of MHD
In this innovative study, a unique approach was engaged to simulate the flow characteristics of nanofluid inside a tank featuring a surface subjected to uniform flux. The testing fluid for this investigation was fabricated by incorporating alumina powders with varying shapes into water. The derivation of the final equations involved the application of Darcy’s law and the formulation of the stream function. The container experienced the combined efficacy of both the Lorentz force and gravity forces. The incorporation of additives resulted in a significant enhancement of the Nusselt number (Nu), demonstrating an increase of 19.8% and 40.28%, contingent on the magnitude of the Hartmann number (Ha). Moreover, an elevation in the shape factor led to a notable rise in Nu by 14%. Remarkably, as the Ha increased, there was a substantial reduction in the cooling rate by 51.33%. Furthermore, in the absence of the Ha, an escalation in the Rayleigh number (Ra) caused Nu to surge by 65.8%. This study holds paramount importance as it introduces a novel technique for simulating nanofluid flow with a sinusoidal surface, providing valuable insights into the complex interplay of forces within the container. The utilization of varying shapes of alumina powders adds a layer of sophistication to the experimentation, making this investigation a noteworthy contribution to the existing body of knowledge. The findings not only enhance our understanding of heat transfer dynamics but also offer practical implications for applications involving nanofluids in containers with nonuniform surfaces subjected to heat flux.

期刊介绍: Launched in 1987, the International Journal of Modern Physics B covers the most important aspects and the latest developments in Condensed Matter Physics, Statistical Physics, as well as Atomic, Molecular and Optical Physics. A strong emphasis is placed on topics of current interest, such as cold atoms and molecules, new topological materials and phases, and novel low dimensional materials. One unique feature of this journal is its review section which contains articles with permanent research value besides the state-of-the-art research work in the relevant subject areas.
