TURBOMACHINE SUCH AS A COMPRESSOR OR PUMP COMPRISING MEANS FOR IMPROVING ITS PART-LOAD BEHAVIOUR

摘要

The invention relates to a method of improving the part-load behavior of a turbo machine operating with a rotor 13 having fixed vanes 14. Such method uses the feature of applying auxiliary fluid injection nozzles 18 near the inlet 11 of the rotor for adding a small amount of fluid to the main fluid flow. The additional amount of fluid is projected in direction such that a substantial velocity component of the movement of this additional fluid is directed tangentially with respect to the rotation of the rotor 13.
