摘要
采用五孔球探针测量了不同排气结构参数(导流锥下口直径d1、开缝面积比a和开缝位置)的改变对PSC-100型导叶式旋风管内总压降和流场的影响。试验结果表明:带有导流锥的排气结构对分离有利;导流锥下口直径增大,气流旋转强度减小,颗粒分离所需离心力场减弱;导流锥开缝面积越大,分离空间内气旋强度越低;导流锥上侧缝开缝部位对旋风管内流场分布亦有影响。
By means of the intelligent five-hole pitot tube, the exhaust structure influence from the lower port d1, the slotted area ratio a and the slotted position on the flow field distribution were investigated. Experimental results show that, an exhaust structure with diversion cone benetits centriiugal separation; with the enlarge- ment of lower port d1 , the gas rotation intensity slows down and the centrifugal force to particle separation decreases; the gas rotation intensity slows down with the reduce of slotted area. The slotted position also influences flow field distribution.
