Twelve casing configurations were investigated , consisting of three step profiles at each of three clearance levels ( including seven casing geometric size ) to find the effects of radial / axial variation of tip gap on rotor performance , and five casing configurations including two types of asymmetric profiles were applied in the research of circumferential variation of tip clearance 文中設(shè)計(jì)了十二種機(jī)匣結(jié)構(gòu)用于與實(shí)壁機(jī)匣相比較,包括軸向布局的七種階梯狀結(jié)構(gòu)及五種周向變化的不對稱結(jié)構(gòu)形式(偏心周向變化和橢形周向變化) 。
