Rezumat: A preliminary design efficiency optimization of a multistage axial flow compressor is studied in this paper using one-dimensional flow theory. A model for the optimum design of a multistage axial flow compressor, assuming a fixed distribution of axial velocities is presented. The absolute inlet and exit angles of the rotor of every stage are taken as the design variables. Analytical relations between the isentropic efficiency of the multistage compressor and the flow coefficient, the work coefficient, the flow angles and the degree of reaction of every stage are obtained. The results have some generalizations and can provide some guidance for the optimum design of multistage compressors.
