Abstract

Purpose

The complex behavior of viscoelastic fluids and its flow analysis under the impact of transverse magnetic field are becoming increasingly important in numerous emerging applications including biomedical engineering, aerospace engineering, geophysics and industrial applications. Additionally, the thermal analysis and fluid flow driven by propagating membranes will aid significant applications for microscale transport in bio-thermal systems. This study aims to investigate the thermal effects of viscoelastic fluids driven by membrane-induced propagation and transverse magnetic field.

Design/methodology/approach

The propagation of the membranes will work as pump which pushes the fluids from bottom to top against the gravitation force; however, there is backflow due to compression and expansion phases of membrane propagation. The Jeffrey fluid model is employed to analyze the viscoelastic fluid flow, with entropy generation examined and equations solved analytically under low Reynolds number and long-wavelength assumptions.

Findings

The findings reveal that an increase in magnetic field strength impedes fluid flow, while higher values of the Grashof number, heat source parameter and Jeffrey fluid parameter enhance fluid motion. The study’s findings have significant implications for optimizing magnetohydrodynamic systems in various emerging applications, including biomedical engineering, aerospace, geophysics and industrial processes.

Originality/value

This study aims to investigate the impact of a transverse magnetic field on the flow and heat transfer characteristics of viscoelastic fluids driven by membrane propagation.

粘弹性流体的膜驱动流动和传热:多流体力学和熵生成分析
在生物医学工程、航空航天工程、地球物理和工业等众多新兴应用中,粘弹性流体的复杂行为及其在横向磁场作用下的流动分析变得越来越重要。此外,热分析和由繁殖膜驱动的流体流动将有助于生物热系统中微尺度运输的重要应用。本研究旨在探讨膜诱导传播和横向磁场驱动下粘弹性流体的热效应。设计/方法/方法膜的传播就像泵一样,在重力的作用下将流体从底部推到顶部;然而,由于膜传播的压缩和膨胀阶段存在回流。采用Jeffrey流体模型对粘弹性流体流动进行了分析,在低雷诺数和长波长假设条件下,对方程进行了解析求解。结果表明:磁场强度的增大会阻碍流体的流动,而格拉什夫数、热源参数和杰弗里流体参数的增大则会增强流体的运动。该研究结果对优化各种新兴应用中的磁流体动力学系统具有重要意义,包括生物医学工程、航空航天、地球物理和工业过程。独创性/价值本研究旨在探讨横向磁场对膜传播驱动粘弹性流体流动和换热特性的影响。
