摘要

研究了复合狭窄、外磁场和对流换热作用下可渗透微循环的血流。血液的双层模型由核心区域的流体颗粒悬浮液和外周无细胞的血浆层组成。对所提出的方程组进行了求解并绘制了图形。在存在可渗透壁面、外加磁场和对流换热的情况下,研究了血液的温度、摩擦系数雷诺数和努塞尔数。当哈特曼数增加、达西数增加、红细胞压积水平增加或外周层变薄时,血液温度升高。摩擦系数雷诺数积随着红细胞压积、哈特曼数、狭窄高度和达西数的增加而增大。Nusselt数随Hartmann数、红细胞压积、狭窄高度或Darcy数的增加而降低。这些结果是根据实际情况来解释的。这项研究有助于了解壁透性、磁场和热传递对未来不同病变动脉系统的影响。

CONVECTIVE HEAT TRANSFER ON STENOSED BLOOD FLOW THROUGH PERMEABLE MICROCIRCULATION IN THE PRESENCE OF A MAGNETIC FIELD
Blood flow through permeable microcirculation in the presence of a composite stenosis, an external magnetic field and convective heat transfer was examined. A two-layered model for the blood consisting of a fluid-particle suspension in the core region with a peripheral cell-free plasma layer was used. The proposed system of equations was solved and plots were generated. In the presence of permeable walls, an external magnetic field and convective heat transfer, the temperature of the blood, friction-factor Reynolds number and Nusselt number were investigated. The temperature of the blood increased when the Hartmann number increased, Darcy number increased, haematocrit level increased or the peripheral layer thinned. The friction-factor Reynolds number product increased as the haematocrit, Hartmann number, stenosis height or Darcy number increased. The Nusselt number decreased as the Hartmann number, haematocrit, stenosis height or Darcy number increased. These results were interpreted in terms of the physical situation. This study aids in understanding the effects of wall permeability, a magnetic field and the presence of heat transfer on different diseased arterial systems in the future.
