在光学薄流体假设下，对病变动脉中传热对血液运动的影响进行了建模。得到了体积流速率、换热速率和管壁剪切应力的封闭解析解。研究表明，除了血管收缩和磁场的作用外，热量传递还会影响心血管系统的血液流动。这种影响在速度和温度分布中是明显的。该模型清晰地显示了发热状态下动脉狭窄患者的情况。(c) 2005 Elsevier Ltd版权所有。
The effect of heat transfer on the motion of blood in a diseased artery has been modeled under the optically thin fluid assumption. Closed-form analytical solutions are obtained for the volume flow rate, rate of heat transfer and shear stress at the vessel wall. The study shows that, in addition to the constriction of the blood vessel and the effect of a magnetic field, the heat transfer also affects the blood flow in the cardiovascular system. This effect is noticeable in the velocity and temperature distributions. The model clearly shows the situation of a patient with a stenosed artery under feverish condition. (c) 2005 Elsevier Ltd.
