Computational Study in Centrifugal Compressor
Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 3
Abstract
The active control for centrifugal compressor systems consists in using, monitoring and managing the sensors to detect fluid disturbances, the actuators to introduce desired perturbations and a suitable controller to determine the optimal actuator actions using the sensor information. The object of an interesting centrifugal compressor design is to obtain the most air through a given diameter compressor, with a minimum number of stages while maintaining high efficiencies and aerodynamic stability over the operating range. The high efficiency of the axial compressor system decreases dramatically when used in small high-pressure applications, especially due to the large relative tip clearance. In addition, the high centrifugal force, dominating the pressure rise, results in a superior operability and the short axial length of the centrifugal compressor offers rotor-dynamic multiple advantages. These qualities allow the centrifugal compressor system to be used as the last stage of a high-pressure compressor of an aero engine as well as turbo pump assemblies used in liquid-propelled rocket engines.
