Abstract

Abstract Blood flow in narrow channels such as veins and arteries is the major topic of interest here. The Casson fluid with its shear-thinning attribute serves as the blood model. Owing to the arterial walls, the channel is configured curved in shape. The activation energy and nonlinear thermal radiation aspects are highlighted. The channel boundaries are flexible with peristaltic wave travelling along the channel. The mathematical description of the problem is developed under physical laws and then simplified using the lubrication technique. The obtained system is then sketched in graphs directly using the numerical scheme NDSolve in Mathematica software. The physical interpretation of parameters on axial velocity, temperature profile, concentration, and streamline pattern is discussed in the last section.

基于活化能和非线性热辐射的窄通道血流分析

在狭窄的通道如静脉和动脉中的血流是这里感兴趣的主要话题。卡森流体以其剪切稀化特性作为血液模型。由于动脉壁的作用，通道呈弯曲形状。重点介绍了活化能和非线性热辐射两个方面。随着蠕动波沿通道传播，通道边界是柔性的。该问题的数学描述是在物理定律的基础上发展起来的，然后用润滑技术进行了简化。然后直接使用Mathematica软件中的NDSolve数值格式将得到的系统绘制成图形。最后一节讨论了轴向速度、温度分布、浓度和流线模式等参数的物理解释。

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation.
