Rotordynamic Fluid Force Moments on an Open-type Centrifugal Compressor Impeller in Precessing Motion
Published 2001-01-01“…In this paper, following results are obtained: (1) The fluid force moment becomes destabilizing in the region of negative precessing speed ratio (-0.3<Ω/ω<0), at the design flow rate; (2) At reduced flow rate, the destabilizing fluid force moments occurred at small positive precessing speed ratio (0.2<Ω/ω<0.4); (3) From the comparison of direct measured fluid force moments with those estimated from the unsteady pressure measured on the front and back casing walls, it was found that the destabilizing moments in the backward precession are mainly caused by the fluid forces on the front surface of the present impeller, where there is large clearance between the back shroud and casing.…”
