Abstract

The main target of this article is to analyze the role of activation energy and thermal radiation effects on the bioconvective peristaltic transport of Sutterby nanofluid in a two-dimensional flexible porous channel with heat and mass transfer. Also, the consequences of Hall current, heat source, and complaint wall properties along with an inclined magnetic field are taken into consideration. The proposed system of governing equations is simplified by using lubrication approximation and solved numerically using MATLAB's bvp5c solver. Further, numerical observations are analyzed to figure out the consequence of different physical parameters on the flow characteristics. According to the observations, it is identified that the Sutterby nanofluid velocity declines with the climb in the damping force parameter, while it enhances with the upsurge in the Darcy number. The Sutterby fluid temperature profile strengthens when the influence of the heat generation and Brinkman number increase, while it depicts the reverse effect with the elevation in the fluid parameter and radiation parameter. The temperature ratio and activation energy parameters were found to have a significant impact on the fluid concentration. The volume of the trapped fluid bolus is an enhancing function of the channel's non-uniformity parameter. Moreover, current work reveals its applicability to recognize the hemodynamic flow analysis and other biofluid movements in the human body and industrial sectors.
水磁性萨特比纳米流体通过带有陀螺仪微生物的化学活化多孔通道的生物对流蠕动输送
本文的主要目标是分析活化能和热辐射效应对 Sutterby 纳米流体在二维柔性多孔通道中进行热量和质量传递的生物对流蠕动传输的作用。此外,还考虑了霍尔电流、热源、抱怨壁特性以及倾斜磁场的影响。通过使用润滑近似简化了所提出的控制方程系统,并使用 MATLAB 的 bvp5c 求解器进行了数值求解。此外,还对数值观测结果进行了分析,以找出不同物理参数对流动特性的影响。观察结果表明,萨特比纳米流体的速度会随着阻尼力参数的增大而减小,而随着达西数的增大而增大。当发热量和布林克曼数增加时,萨特比流体的温度曲线会增强;而当流体参数和辐射参数升高时,萨特比流体的温度曲线会出现相反的效果。研究发现,温度比和活化能参数对流体浓度有显著影响。截留流体的体积是通道非均匀性参数的增强函数。此外,目前的工作还揭示了它在识别人体和工业领域的血液动力学流动分析和其他生物流体运动方面的适用性。
