dc.description.abstract | Centrifugal compressors are at times required to operate in or
near the choke region. Various limits of the degree of allowable
operation in choke have been established. Based on test data
and numerical data, the behavior of centrifugal compressors in
the choke region is studied. Changes in aerodynamic
performance, thrust load, volute behavior and radial loading are
considered. The issue of excitation of impeller vanes is
addressed. Particular consideration is given to multistage
machines, as well as dual compartment machines, in particular
regarding the effects of impeller mismatch during operating
conditions at flows significantly higher than the design flow.
Limitations in the overload operating range of a compressor not
only impact the operational flexibility , but also can require
more complicated control systems. The paper addresses
aerodynamic, structural as well as rotordynamic issues related
to the operation in choke. | en |
