The Effect of Reaction on Compressor Performance

Abstract Reaction is the fundamental parameter by which asymmetry of velocity triangle a stage set. Little understood about effect that reaction has on either efficiency or operating range compressor. A particular difficulty in understanding rotor and stator have natural caused centrifugal effects boundary layer being much larger than layer. In this paper, novel approach been taken: McKenzie’s “linear repeating stage” concept used to remove effects. The are then reintroduced as body force. This allows force be decoupled. paper shows surprising result that, depending how solidity set, 50% can maximum, minimum, profile loss. When removed, shown minimize endwall loss, maximize efficiency, range. reintroduced, compressor with maximum design found rise 5% (from 55% reaction) 15% 65% reaction).
