Abstract

A NUMERICAL OPTIMIZATION is undertaken for preliminary aerodynamic design of AXIAL COMPRESSORS. Initially, design process is performed based on calculations along mean line. Then, results of geometric parameters and gas dynamic characteristics are extended to different radial positions distributed from blade root to its tip using well-known radial equilibrium law. In the process of optimization, pressure ratio of each stage of multistage compressor has been taken as design variables. Constraints consist of well known DE-HALLER NUMBER of each stage as a criterion for flow failure. Main input data consist of overall pressure ratio, mass flow rate and rotational speed. Compressor efficiency is treated as the objective function which is a nonlinear function of the variables. The main objective of present research work is to optimize initial pressure ratio distribution in order to maximize the overall isentropic efficiency. The optimization approach is based on the use of REDUCED GRADIENT PROJECTION Method. The proposed method was tested on a known example of a compressor design from the literature, and is shown to enhance the efficiency with good agreement with the published results.
