轴流风机油流显示实验研究

Oil flow visualization experiment research on axial flow fan

流动显示技术是流体力学和空气动力学研究中常用的重要实验手段,把流动显示实验方法中的油流显示技术应用到轴流风机内部流动研究中,成功地捕捉到了轴流风机中的流动分离线及其二次流动的流动现象。使我们可以通过简单易行的表面油流显示技术来取得复杂流动现象中许多重要的信息。

Flow visualization technology is one of the most important experiment methods frequently used in studying of fluid mechanics and air dynamics. Oil flow visualization technology, one of most used flow visualization experiment method , was utilized in the research on inner-flow of axial flow fan in this article. Sep arated flow line and second flow are successfully captured in this experiment. By means of the simple surface oil flow visualization method we can capture many im-portant information of complex flow phenomenon.
