This research discusses the merged effect of homogeneous-heterogeneous reactions on the peristaltic mechanism of hyperbolic tangent fluid in a curved compliant channel in the presence of slip effects. Transport of heat is developed by using the heat conduction model proposed by Fourier with viscous dissipation effect. The derived coupled system of partial differential equations have been simplified under long wavelength assumptions. Keeping in mind of the considered problem assumptions, it is found that the governing system of fluid flow equations are coupled and highly non-linear. A perturbation technique is applied for small Weissenberg number to find out the series solution for stream function, momentum, thermal, concentration distributions, and heat transfer coefficient. The influence of numerous parameters associated with flow characteristics such as Brinkman number, Prandtl number, Hartman number, and slip which are explained in detail and also, plotted the graph for velocity, concentration and temperature distribution. The expressions for skin friction coefficient and Nusselt number at the complaint wall are found and evaluated. It is worth mounting that augmenting values of velocity slip and elastic parameters reduces the fluid velocity, whereas, thermal profile upsurges against the mounting values of slip parameter. Moreover, it is recorded the elastic parameter has reverse behavior on thermal field as compared with brinkman number. The scope of the present article is valuable in explaining the blood transport dynamics in small vessels while considering the important wall features with chemical reaction characteristics.

正弦波状波状通道中均相-非均相反应效应的Meta分析

本研究讨论了在存在滑移效应的情况下,均相-非均相反应对双曲正切流体在弯曲顺应通道中蠕动机理的合并作用。通过使用傅立叶提出的具有粘性耗散效应的导热模型来开发热量的传递。在长波长假设下,简化了导出的偏微分方程耦合系统。考虑到所考虑的问题假设,发现流体流动方程的控制系统是耦合的并且是高度非线性的。将扰动技术应用于较小的Weissenberg数,以找到关于流函数,动量,热,浓度分布和传热系数的级数解。与流动特性相关的许多参数的影响,例如布林克曼数,普朗特数,哈特曼数和滑度,将详细说明,并绘制速度,浓度和温度分布图。找到并评估了抱怨壁上的皮肤摩擦系数和努塞尔数的表达式。值得一提的是,增加速度滑移和弹性参数的值会降低流体速度,而热剖面却会相对于滑移参数的安装值激增。此外,记录的弹性参数与布林曼数相比在热场上具有相反的行为。
