The Navier-Stokes equations are solved numerically for steady flow through a double-branched two-dimensional section of a three-dimensional model of a canine aorta for which experimental data is available. The numerical scheme involves transforming the physical coordinates to a curvilinear boundary-fitted coordinate system and performing finite-difference computations in the transformed system. Shear stress at the wall is calculated for a Reynolds number of a 1,000 with branch-to-main aortic flow rate ratios as a parameter. The results are compared with the aforementioned experimental data and show reasonable qualitative agreement.
针对犬主动脉三维模型的二维双分支截面中的稳定流动，对纳维 - 斯托克斯方程进行了数值求解，该模型有可用的实验数据。数值方案包括将物理坐标转换为曲线边界拟合坐标系，并在转换后的系统中进行有限差分计算。以分支与主动脉主流流速比为参数，计算了雷诺数为1000时壁面的剪应力。将结果与上述实验数据进行比较，显示出合理的定性一致性。
