Compressor Off-Design Operation

  • Klaus H. Lüdtke
Chapter

Abstract

This chapter contains a methodical description and comparison of the five regulation modes: variable speed, suction throttling, adjustable inlet guide vanes, adjustable diffuser vanes and cooled bypassing. Two more topics are discussed. First, there is the test deducted dimensionless performance curve, showing work input factor versus exit flow coefficient, remaining (nearly) invariant by any transformations of speed, temperature and even gas composition. Second, there is the publication of test results in the expansion mode, i.e. the operation of a compressor stage beyond its choke point.
