The current work analyzes the effects of concentric ballooned catheterization and heat transfer on the hybrid nano blood flow through diseased arterial segment having both stenosis and aneurysm along its boundary. A fractional second-grade fluid model is considered which describes the non-Newtonian characteristics of the blood. Governing equations are linearized under mild stenosis and mild aneurysm assumptions. Precise articulations for various important flow characteristics such as heat transfer, hemodynamic velocity, wall shear stress, and resistance impedance are attained. Graphical portrayals for the impact of the significant parameters on the flow attributes have been devised. The streamlines of blood flow have been examined as well. The present finding is useful for drug conveyance system and biomedicines.
目前的工作分析了在病变动脉段存在狭窄和动脉瘤的情况下，同心球囊导管和传热对混合纳米血流的影响。考虑了一个分数阶二级流体模型，用于描述血液的非牛顿特性。在轻度狭窄和轻度动脉瘤假设下，对控制方程进行了线性化处理。获得了各种重要流动特性的精确表述，如传热、血液动力学速度、壁面剪切应力和阻力阻抗。设计了图形表示，以显示重要参数对流动特性的影响。还检查了血流的流线。本研究结果对药物输送系统和生物医学具有重要意义。
