摘要

本文研究了在有粉尘存在的多孔介质中，耦合应力对从下加热的微极流体层的影响。利用正交模态技术推导了色散关系，并分析了孔隙度、磁场、粉尘颗粒、耦合应力参数和微极性参数的影响。利用MATLAB得到了数值解。尘埃颗粒的影响是该模型的一个非常重要的结果。这些结果与以往的工作进行了比较，结果很吻合。

A study of the couple stress on micropolar fluid flow saturating a porous medium in the presence of dust particles with hall current

In this paper, the effect of couple stress on the micropolar fluid layer heated from below in the presence of dust particles through the porous medium with hall current has been investigated. The dispersion relation is derived using the normal mode technique, and the influences of porosity, magnetic field, dust particles, couple stress parameter, and micropolar parameters are analyzed both analytically and numerically. The numerical solutions are obtained using MATLAB. The impact of dust particles is a very important result of this model. These results have been compared with previous work, and they are in good agreement.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
