过程设备冷态流场激光测量示踪粒子选择与添加

Particle selecting and providing techniques for laser measurement on the flow field of process equipment

示踪粒子选择是用激光仪器进行流动测量的关键,对于不同工艺过程的设备,其粒子选择和添加技术也不同。通过几个用APV进行流动测量的实例,讨论了过程设备流场测试中粒子选择与添加的基本原则。

?The proper selection of particles is the key to make successful measurement for laser velocimeters,and particle selecting and providing techniques vary with different process equipmentThrough several measurement examples by the APV (adaptive phase/doppler velocimeter)system the principles of particle selecting and providing are discussed for measurement on the flow field of process equipment
