Abstract: 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.
