Abstract

The principal purpose of the current investigation is to indicate the behavior of the tangent-hyperbolic micropolar nanofluid border sheet across an extending layer through a permeable medium. The model is influenced by a normal uniform magnetic field. Temperature and nanoparticle mass transmission is considered. Ohmic dissipation, heat resource, thermal radiation, and chemical impacts are also included. The results of the current work have applicable importance regarding boundary layers and stretching sheet issues like rotating metals, rubber sheets, glass fibers, and extruding polymer sheets. The innovation of the current work arises from merging the tangent-hyperbolic and micropolar fluids with nanoparticle dispersal which adds a new trend to those applications. Applying appropriate similarity transformations, the fundamental partial differential equations concerning speed, microrotation, heat, and nanoparticle concentration distributions are converted into ordinary differential equations, depending on several non-dimensional physical parameters. The fundamental equations are analyzed by using the Rung-Kutta with the Shooting technique, where the findings are represented in graphic and tabular forms. It is noticed that heat transmission improves through most parameters that appear in this work, except for the Prandtl number and the stretching parameter which play opposite dual roles in tin heat diffusion. Such an outcome can be useful in many applications that require simultaneous improvement of heat within the flow. A comparison of some values of friction with previous scientific studies is developed to validate the current mathematical model.

摘要

当前研究的主要目的是表明双曲正切微极纳米流体边界层在通过渗透介质的延伸层上的行为。该模型受正常均匀磁场的影响。考虑了温度和纳米颗粒的质量传递。还包括欧姆耗散、热源、热辐射和化学影响。当前工作的结果对于边界层和拉伸板问题,如旋转金属、橡胶板、玻璃纤维和挤出聚合物板等具有实际重要性。当前工作的创新之处在于将双曲正切流体和微极流体与纳米颗粒分散相结合,这为这些应用增添了新趋势。通过应用适当的相似变换,关于速度、微旋转、热和纳米颗粒浓度分布的基本偏微分方程被转换为常微分方程,这取决于几个无量纲物理参数。使用龙格 - 库塔射击技术对基本方程进行分析,结果以图形和表格形式呈现。可以注意到,除了普朗特数和拉伸参数在热扩散中起相反的双重作用外,通过这项工作中出现的大多数参数热传递都会增强。这样的结果在许多需要同时改善流体内热量的应用中可能是有用的。与先前科学研究的一些摩擦值进行比较,以验证当前的数学模型。
