Arteries in the upper limb play important roles in the circulation system of the human body. In particular, the radial artery has received considerable attention in traditional Chinese medicine for thousands of years. Here, a 3D model for the arm arteries has been created uncomplicated, in a Chinese adult's left hand, from the magnetic resonance imaging data, using professional modeling software to restore the basic structure of the arm artery in human body, before being imported to Ansys software for simulation. Blood model has been only simulated, and using the blood density of constant parameter and viscosity using the Carreau fluid model, and using viscous-laminar model of Fluent to obtain the velocity profile, static pressure and shear stress in the brachial, interosseous, ulnar, radial and palmar arch arteries. In particular, the brachial and bifurcations have the high pressure and velocity profiles. The simulation results obtained here are also validated by those published in the literature and proved the ulnar artery prevails over the radial artery as a blood supplier to the vessels in the wrist and hand.
上肢动脉在人体循环系统中发挥着重要作用。特别是，桡动脉在中医领域已经受到了数千年的广泛关注。在此，利用专业建模软件，基于磁共振成像数据，在一位中国成年人的左手创建了一个简单的手臂动脉三维模型，以还原人体手臂动脉的基本结构，然后将其导入Ansys软件进行模拟。仅对血液模型进行了模拟，使用Carreau流体模型设置恒定参数的血液密度和粘度，并采用Fluent的粘性层流模型来获取肱动脉、骨间动脉、尺动脉、桡动脉和掌弓动脉中的速度分布、静压和剪应力。特别是，肱动脉及其分支处具有较高的压力和速度分布。此处获得的模拟结果也得到了文献发表结果的验证，证明在为手腕和手部血管供血方面，尺动脉优于桡动脉。
