Abstract

This report describes the aerodynamic design of centrifugal compressors.The design approach is based on Jet and Wake model with suitable loss correlation in it.The method incorporates a matching inducer and diffuser design for optimum compressor performance.For given input parameters like mass flow rate and pressure ratio the design programme generates a 3-d impeller with optimised aerodynamic parameters.A Computer programme was developed based on the above method.Using this computer programme radial and back swept impellers to develop a pressure ratio of 6.0 to 0.96kg/sec were designed.This design method explained in this report is one step improvement on one dimensional design approach used widely.
