Gas Flow and Distribution in Circle Distributor
摘要
Abstract
The fluid field in a gas distributor with a rectifying ring was measured with LDV.In the outer passage,there was a great deal of circulation gas and the flow was in variablemass way.In the inner passage,the circulation gas was eliminated,but the velocity impulsed strongly.Gas flowed in radial direction uniformly nearby the pores on the wall of center pipe.The influence of the opening ratio and the opening mode of the rectifying ring on the gas distribution effect was also measured with a calandria manometer.The flow through the pores of the center pipe could be uniformly distributed by adjusting the opening ratio of the rectifying ring.In the range of this experiment,the energy loss of the distributor could be decreased with the rectifying ring.关键词
