This paper presents a model of nonisothermal blood flow through a diseased arterial segment due to the presence of stenosis and thrombosis. The rheological properties of the blood in the annulus are captured by utilizing micropolar fluid model. The equation describing the blood flow and heat transfer is developed under the assumption that stenosis growth into the lumen of the artery is small as compared to the average radius of the artery. Biological processes like intimal proliferation of cells or changes in artery caliber may be activated by small growths that cause moderate stenotic blockages. Closed-form solutions for temperature, velocity, resistance impedance and wall shear stress are obtained and then utilized to estimate the impact of various physical parameters on micropolar blood flow. Graphs are plotted to illustrate variations in temperature, velocity, shear stress at the wall and resistance impedance against different controlling parameters. The results are also validated via the bvp4c approach.

本文提出了由于狭窄和血栓形成而穿过患病动脉段的非等温血流模型。利用微极性流体模型捕获环带中血液的流变特性。描述血流和热传递的方程是在假设动脉管腔内的狭窄增长与动脉的平均半径相比较小的情况下建立的。诸如内膜细胞增殖或动脉管径变化之类的生物过程可能会被导致中度狭窄阻塞的小生长激活。获得温度、速度、电阻阻抗和壁剪切应力的闭合解，然后用于估计各种物理参数对微极血流的影响。绘制图表来说明温度、速度、壁上的剪切应力和电阻阻抗相对于不同控制参数的变化。结果还通过 bvp4c 方法进行了验证。
