摘要

本文旨在研究普朗特纳米液体在倾斜锥形非对称通道中的蠕动运动。同时考虑了磁场、热辐射和化学反应等效应。几何模型被认为是锥形不对称通道,因为这种情况是在子宫内子宫液的流动中观察到的。在长波长和低雷诺数的假设下,对流动方程进行了简化。简化后的方程本质上是复杂的,因此利用计算软件Mathematica通过射击法对考虑滑移和对流边界条件的简化非线性偏微分方程进行数值求解。通过图形和表格的形式详细讨论了影响流量的各种参数。观测结果表明,磁效应的增强导致速度的减小。辐射参数使温度降低,压力梯度随能量格拉什夫数的增加而增大。本研究旨在探索以生物流动中的热传递、新型药效学泵和胃肠道运动增强为标志的蠕动运输中的纳米流体动力学。

Biomechanical study of magnetohydrodynamic Prandtl nanofluid in a physiological vessel with thermal radiation and chemical reaction
This article is intended to study the peristaltic motion of a Prandtl nanoliquid through an inclined tapered asymmetric channel. The simultaneous effects such as magnetic field, thermal radiation and chemical reactions have been considered. The geometrical model is considered as tapered asymmetric channel because this situation is observed in the flow of uterine fluid in the uterus. The equations governing the flow are simplified under the assumptions of long wavelength and low Reynolds number. The simplified equations are complex in nature, so that the numerical solutions are presented for the simplified nonlinear partial differential equations considering slip and convective boundary conditions using computational software Mathematica via shooting method. The sundry parameters on the flow quantities have been discussed in detail through graphical and tabular forms. The observed results show that rise in the magnetic effects leads to a reduction in velocity. The radiation parameter decreases the temperature and there is an increment in the pressure gradient with an increase in energy Grashof number. This study is encouraged by exploring the nanofluid dynamics in peristaltic transport as symbolized by heat transport in biological flows, novel pharmacodynamic pumps and gastrointestinal motility enhancement.
