探讨了柔性通道内Rabinowitsch流体模型中的非均相-非均相反应对渗透输运机理的影响。对Rabinowitsch流体模型（添加粘度指数改进剂的润滑油）的温度、速度和浓度分布进行了数学建模和分析，探讨了影响参数与动态阻尼和刚度特性的关系。本文的范围在解释血管中的血流动力学方面是有价值的，同时考虑了血管壁的基本特征和化学反应。该模型可以描述磁场、化学反应和速度滑移对血管壁的影响。用润滑方法建立了偏微分方程组。在柔性壁的努塞尔数和表面摩擦系数的表达式被发现和评估。均相和非均相反应参数对浓度场的影响表现为相反的趋势。此外，增加的表面摩擦力是通过增加刚度和阻尼的参数值。(c)2020年，任作家。由爱思唯尔公司出版。这是一篇开放获取的文章，获得了CC BY-NC-ND许可证（http：//creativecommons.org/licenses/by-nc-nd/4.0/）。
This exploration addresses the comportments of homogeneous-heterogeneous reactions on peristalsis transportation mechanism of Rabinowitsch fluid model inside a flexible channel. Mathematical modelling and analysis are performed for temperature, velocity and concen- tration distributions to explore the bearing of influential parameters for Rabinowitsch fluid model (lubricant blended with viscosity index improver) with the dynamic damping and stiffness characteristics. The scope of the current article is valuable in explaining the blood flow dynamics in vessels while considering the essential wall characteristics and chemical reaction. The effects of magnetic field, chemical reaction and velocity slip in blood vessels wall can be described by the presented model. The partial differential equations are formu- lated by the use of lubrication approach. The expressions for Nusselt number and coefficient of skin friction at the flexible wall are found and evaluated. The effects of homogeneous and heterogeneous reaction parameters shows reverse comportment on concentration field. Moreover, augmentation in skin friction is notice by escalating the parametric values of rigidity and damping. (c) 2020 The Authors. Published by Elsevier B.V.
