A new technique for visualizing the steady flow of a new type of test fluid is presented that produces quality photographic results at Reynolds numbers typically found in arterial bypass grafts. Room air functions as the test fluid and smoke from burning incense sticks provides the tracer particles. As an example of this new technique, photographic results are presented for a Reynolds number flow of 205 through a Plexiglas model of an end-to-side distal anastomosis with a 45 degrees junction angle. The advantages of this technique are that it is simple, convenient, and applicable to a wide variety of flow conditions found in the human cardiovascular system.
本文介绍了一种可视化新型测试流体稳定流动的新技术，该技术在动脉搭桥移植物中常见的雷诺数下能产生高质量的摄影结果。室内空气作为测试流体，香棒燃烧产生的烟雾提供示踪粒子。作为这项新技术的一个例子，给出了雷诺数为205的流体通过一个夹角为45度的端侧远端吻合术的有机玻璃模型的摄影结果。该技术的优点是简单、方便，适用于人类心血管系统中发现的各种流动条件。
