The paper presents a study related to the two-phase analysis of pulsatile blood flow through a narrowed stenosed artery with radiation and the chemical effects. In the model, a vertical artery is considered in which the flow of blood is assumed vertical upward and the direction of an external applied magnetic is in the radial direction of the flow. To understand the behavior of blood flow, graphs of the velocity profile, wall shear stress, flow rate, flow impedance and concentration profile are portrayed with different values of the magnetic and radiation parameters. In order to validate the results, a comparative study is presented between the single-phase and two-phase model of the blood flow, which shows that the two-phase model fits more accurately with the experimental data than the single-phase model, as mean errors are \(0.3\%\) for the two-phase model while it is \(1\%\) for single-phase model. For pulsatile flow, the phase difference between the pressure gradient and the flow rate is displayed with the effects of the magnetic field and different heights of the stenosis.

本文提出了一项与通过狭窄狭窄的狭窄动脉的脉动血流的两相分析有关的研究，该研究具有辐射作用和化学作用。在该模型中，考虑了一条垂直动脉，其中假定血流垂直向上，并且外部施加的磁力的方向是沿血流的径向。为了了解血流的行为，用不同的磁和辐射参数值绘制了速度分布图，壁面剪切应力，流速，流动阻抗和浓度分布图。为了验证结果，在单相和两相血流模型之间进行了比较研究，结果表明，与单相模型相比，两相模型与实验数据更准确地拟合，因为平均误差是两相模型为\（0.3 \％\），而单相模型为\（1 \％\）。对于脉动流，在磁场和狭窄高度不同的影响下，显示压力梯度和流速之间的相位差。
