Abstract

Optimizing a variety of industrial and biological processes requires an understanding of peristalsis’s mass and heat transmission. The importance of Eyring-Powel liquid flow in a compliant curved channel with peristalsis is examined in this work, particularly in relation to mass and heat transfer, which is crucial for creating effective systems in chemical and biological engineering applications. The flow of a Powell-Eyring liquid across compliant curved channel walls is investigated using a modified Darcy resistance model that accounts for channel porosity, peristalsis, heat generation/absorption, chemical reaction, and mixed convection. The flow formulation is made simpler by assuming large wavelengths and low Reynolds numbers and the solution is found via a built-in numerical procedure. The findings indicate that while temperature rises as thermal slip values vary from 0 to 0.06, velocity decreases when the velocity slip parameter is increased from 0 to 0.03, and concentration reduces with an increasing solutal slip parameter from 0 to 0.09. Furthermore, the rate of mass and heat transmission decreases as the Darcy parameter increases. Understanding the peristaltic flow of fluids via porous and compliant channels can aid in the design of more effective medication delivery systems by optimizing the distribution of medicinal drugs.

修正达西定律和热致化速度下Eyring-Powell液体通过多孔蠕动壁的热行为

优化各种工业和生物过程需要了解蠕动的质量和热量传递。在这项工作中，研究了埃林-鲍威尔液体在具有蠕动的弯曲通道中流动的重要性，特别是在质量和传热方面，这对于在化学和生物工程应用中创建有效的系统至关重要。采用改进的Darcy阻力模型研究了Powell-Eyring液体在弯曲的通道壁上的流动，该模型考虑了通道孔隙度、蠕动、热生成/吸收、化学反应和混合对流。通过假设大波长和低雷诺数使流动公式变得简单，并通过内置的数值程序找到解决方案。结果表明：热滑移值在0 ~ 0.06范围内温度升高，速度滑移参数在0 ~ 0.03范围内速度减小，溶质滑移参数在0 ~ 0.09范围内浓度减小。此外，随着达西参数的增大，传质率和传热率减小。了解流体通过多孔和柔顺通道的蠕动流动可以通过优化药物分配来帮助设计更有效的药物输送系统。

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
