Essay

This thesis is dedicated to techniques for extending the stable flow range of centrifugal compressor stages with vaneless diffusers. Mathematical model for gas flow in vaneless diffuser with mass, momentum angular momentum and energy addition is presented. The results from numerical simulations and experiments are reported. It was shown that injection in vaneless diffusers improves the stable flow range. Comparing the results of simulations and experiments it was shown that the presented mathematical model is adequate and accurate.
