在长波长和低雷诺数假设下，研究了热跃和倾斜磁场对含银纳米颗粒Jeffrey流体在偏心环道中蠕动输运的影响.在医学研究中，热跳跃和倾斜磁场对公共健康的影响令人感兴趣。蠕动运动传递热量和产生磁场的能力在生物医学和生物工程中有多种用途。考虑了含有银纳米颗粒的非牛顿Jeffrey流体在两个偏心排列的圆柱管之间的空间中的流动。同伦摄动法是一种半解析方法，适用于建模和非线性偏微分方程（HPM）。为了说明物理参数如何影响温度、速度、浓度、摩擦力和内外管的压力升高，绘制了曲线图。本方法与温度和纳米颗粒浓度分布的精确解的比较以图形方式示出。本文分析的解析解接近于精确解。在目前的研究中，最有意义的是哈特曼数和热泳数使速度剖面下降。Jeffrey流体参数和磁场角使速度升高。纳米流体的温度由于热跃变而上升。此外，Jeffrey纳米流体具有比Jeffrey流体更高的动量和温度。这种分析可以更好地评估注射器在癌症治疗、动脉阻塞清除和整个手术过程中减少出血的注射速度和流体流动特征。蠕动输运;热跳跃;倾斜磁场; Jeffrey流体;银纳米粒子;偏心圆环
This study investigates the impacts of thermal jump and inclined magnetic field on the peristaltic transport of Jeffrey fluid containing silver nanoparticles in the eccentric annuls under the long wavelength and low Reynolds number assumption. In medical studies, the impact of thermal jumps and slanted magnetic fields on public health is of interest. Peristaltic motion's ability to transmit heat and create a magnetic field has several uses in biomedical and bioengineering. The non-Newtonian Jeffrey fluid with silver nanoparticles is considered in the space between two cylindrical tubes that are eccentrically aligned. The homotopic perturbation method is semi-analytical for modeling and nonlinear partial differential equations (HPM). Analytical solutions for velocity, pressure gradient, and pressure rise were found. To show how physical parameters affect temperature, velocity, concentration, frictional force, and pressure rise of inner and outer tubes were plotted. A comparison of the present method with the exact solution for temperature and nanoparticle concentration profile is shown graphically. The present analysis of analytical solution approaches to the exact solution. The most significant thing in the current investigation is that the Hartmann number and thermophoresis number make the velocity profile decline. Jeffrey fluid parameter and magnetic field angle make the velocity rise. The nanofluid's temperature rises as a result of the thermal jump. In addition, the Jeffrey nanofluid has a higher momentum and temperature than the Jeffrey fluid. This analysis can better evaluate the syringe's injection speed and fluid flow features during cancer treatment, artery blockage removal, and reduced bleeding throughout the surgery.
