摘要

本文研究了磁流体动力两相血液(卡森流体)在血液与颗粒热传导的容器中的流动。还考虑了两相的温度。所考虑的流动模型是用偏微分方程表示的。然后利用卡普托分数阶导数对经典模型进行了推广。然后利用适当的无量纲变量对广义方程进行无量纲化。通过联合应用拉普拉斯和汉克尔积分变换,得到了精确的无量纲解。各种嵌入参数对速度(血液和磁性粒子)和温度分布的影响以图形形式呈现。值得注意的是,在磁疗(用于治疗疼痛,如背部、足部或关节疼痛)和手术过程中,磁参数(H)值的增加有助于控制血流,粒子和血液速度会降低。值得注意的是,分数阶模型通过提供如图所示的病毒积分曲线,比经典模型更好地描述了流动特性。

A Report of Generalized Blood Flow Model with Heat Conduction Between Blood and Particles
This paper examines the magneto hydrodynamic two-phase blood (Casson fluid) flow in a vessel with heat conduction between blood and particles. The temperature of both phases is also considered. The model for the flow under consideration is formulated in terms of partial differential equations. Then the classical model is generalized by utilizing the Caputo fractional order derivative. The generalized equations are then non-dimensional-ized by using appropriate dimensionless variables. The exact dimensionless solutions are obtained via the joint application of Laplace & Hankel integral transforms. The influence of various embedded parameters on both the velocities (blood and magnetic particles) and the temperature distribution are presented graphically. It is worth noting that the particle and blood velocities decrease for increasing the values of magnetic parameter ( H ) which is useful to control the blood flow during magnetic therapy (for treating pain, such as the back, foot, or joint pain) and surgeries. It is worth noting that fractional model better describes the flow behavior than classical model by providing virous integral curves as shown in Fig.
