Abstract Biomimetics is the imitation of the systems, models, and nature elements for the motive of elucidating complex biological problems. In the current century, the use of nanoparticles in the treatment of biological systems (such as cancer and atherosclerosis treatment) is common in worldwide due to many properties of nanoparticles. In general, the size of nanoparticles are very small so that they can pierce extensively throughout the body. Keeping this in mind, the current article focusses the blood (treated as Phan-Thien-Tanner nanofluid) transport in the intrauterine cavity walls under the various effects such as induced magnetic field and solar radiation. For the formulation, the Cartesian coordinate is used, utilizing appropriate transformations and dimensionless quantities, the dimensional laboratory frame system converted to dimensionless wave frame system. The resulting system of equations are highly nonlinear, so we have used the regular perturbation technique to find the solution. Streamlines, velocity, pressure rise, temperature, and concentration have been plotted to see the blood transport in various situations. It is noticed from our analysis that the external effect of radiation enhances the peristaltic pumping. The nanoparticle temperature and concentration are enhanced with the increase of Brownian motion parameter. The sharp reductions in the induced magnetic field are seen with stronger Hartmann number.

感应磁场存在下纳米流体辐射蠕动推进的传热增强

摘要 仿生学是对系统、模型和自然元素的模仿，以阐明复杂的生物学问题。在本世纪，由于纳米粒子的许多特性，纳米粒子在生物系统的治疗（如癌症和动脉粥样硬化的治疗）中的应用在世界范围内很普遍。一般来说，纳米粒子的尺寸非常小，因此它们可以广泛地穿透全身。牢记这一点，本文重点介绍了在感应磁场和太阳辐射等各种影响下宫腔壁中的血液（作为 Phan-Thien-Tanner 纳米流体处理）的运输。对于公式，使用笛卡尔坐标，利用适当的变换和无量纲量，三维实验室框架系统转换为无量纲波框架系统。由此产生的方程组是高度非线性的，因此我们使用了规则扰动技术来寻找解决方案。已绘制流线、速度、压力升高、温度和浓度以查看各种情况下的血液运输。从我们的分析中注意到，辐射的外部效应增强了蠕动泵送。随着布朗运动参数的增加，纳米颗粒的温度和浓度增加。随着哈特曼数的增加，可以看到感应磁场的急剧减少。和浓度已被绘制以查看各种情况下的血液运输。从我们的分析中注意到，辐射的外部效应增强了蠕动泵送。随着布朗运动参数的增加，纳米颗粒的温度和浓度增加。随着哈特曼数的增加，可以看到感应磁场的急剧减少。和浓度已被绘制以查看各种情况下的血液运输。从我们的分析中注意到，辐射的外部效应增强了蠕动泵送。随着布朗运动参数的增加，纳米颗粒的温度和浓度增加。随着哈特曼数的增加，可以看到感应磁场的急剧减少。
