横流中水平浮射流三维运动轨迹测量方法
A measuring method of three-dimensional trajectory of a horizontal buoyant jet in cross flow
摘要
Abstract
The trajectory of a horizontal buoyant jet in cross flow is a three-dimensional and skewed curve.In order to measure the curve,a three-dimensional flow visualization system,which can determine the spatial coordinates of a horizontal buoyant jet trajectory,was designed.The test results show that the horizontal projection trajectory of the threedimensional trajectory is similar to the trajectory of a momentum jet because of the cross flow.Due to the influence of the buoyancy force,the xOz plane projection trajectory of the three-dimensional trajectory is an increasing curve.关键词
