摘要
本文研究了稳燃腔中交叉射流两相流动。使用三维激光粒子动态分析仪 (PDA)测量了正三角形截面副射流与主射流速度比为 2 .5时的交叉射流流动 。
A turbulent triangular jet issuing perpendicularly into a confined gas particle two phase flow was investigated experimentally.When jet to crossflow velocity ratio R equaled to 2 5,mean and fluctuating velocity components were measured by the Three Dimensional Particle Dynamics Anemometry (3 D PDA).The PDA signals were evaluated to yield the turbulent intensity and the particle concentration.The measurement results show that the turbulent intensity in the wake of the crossflow is enhanced particularly on the edge of the recirculation zone.There are two particle concentration peaks,one of them is in the recirculation zone,and the other is on the edge of the zone.
