چکیده:

Design models of axial flow compressor are developed for high temperature power plants with Closed Brayton Cycle for energy conversion. in recent years, manyefforts have been done for modeling and predicting of performance of these compressors on different conditions of speed and pressure ratio because of costly empiricalexperiments, and still are developing. The models are based on a mean-line through-flow analysis for free-vortex flow, accountfor the profile, secondary, end wall and tip clearance losses in the cascades. In this work ,models of Lieblein, Koch-Smith, Herrig, Johnsen-Bullock, Pollard-Gostelow, Aungier, Hunter-Cumpsty, Reneau are implemented to consider single stage compressor losses, stall and surge conditions and calculate thegeometrical parameters of blade cascades. In this regard, following the presentation of solution algorithm , the obtained results of modeling will be examined
