He previously spent 28 years in the Aerodynamics Group, becoming the Supervisor of Aerodynamics in 1984 and promoted to Manager of Aero/Thermo Design Engineering in 2001. Through its optimized aerodynamics, superb process control and Explain the working principle of a centrifugal compressor (Section 21.1) 2. In addition, every plant has different pressure and flow needs. The rotor is fitted with labyrinth seals (L) and, if necessary, oil film end seals (M). It can then be arranged multistage for greater proportions of compression. This causes a rapid, cyclic flow reversal. In this paper, the tip clearance effects on flow field of a low speed centrifugal compressor without and with partial shroud (PS) fitted on to the rotor blade tip at three values of tip clearance, viz.
