Abstract

This paper examine numerical study for soret and dufour effects on unsteady Newtonian MHD fluid flow with mass and heat transfer in a collapsible elastic tube using Spectral Collocation technique. The objective of the study is to determine the velocity, temperature and concentration profiles together with heat and mass transfer rates. The governing equations are continuity, momentum, energy and concentration equation. The system of nonlinear partial differential equations governing the flow solved numerically by applying collocation method and implemented in MATLAB. The numerical solution of the profiles displayed both by graphically and numerically for different values of the physical parameters. The effects of varying various parameters such as Reynolds number, Hartmann number, Soret number, Dufour number and Prandtl number on velocity, temperature and concentration profiles also the rates of heat and mass transfer are discussed. The findings of this study are important due to its wide range of application including but not limited to medical fields, biological sciences and other physical sciences where collapsible tubes are applied.
使用基于光谱的拼合法研究流体流经可折叠管时的索雷特和杜富尔效应
本文采用谱系拼合技术,对可折叠弹性管中带有传质和传热的非稳态牛顿 MHD 流体流动的索氏效应和杜富尔效应进行了数值研究。研究的目的是确定速度、温度和浓度曲线以及传热和传质速率。控制方程包括连续性方程、动量方程、能量方程和浓度方程。通过采用配位法对控制流动的非线性偏微分方程系统进行数值求解,并在 MATLAB 中实现。对于不同的物理参数值,曲线的数值解均以图形和数值方式显示。讨论了不同参数(如雷诺数、哈特曼数、索雷特数、杜福尔数和普朗特尔数)对速度、温度和浓度曲线以及传热和传质速率的影响。这项研究的结果非常重要,因为它的应用范围非常广泛,包括但不限于医学领域、生物科学和其他应用可折叠管的物理科学领域。
