Abstract:
Improvement of axial flow compressor is usually goal of manufacturers of these equipments. Because basic role of it in gas turbine efficiency too many researchers have effort to know phenomenon and effect of them on axial flow compressor's revenue and optimization of them. In this project the aerodynamic of axial flow compressor studied and effect of important parameters such as diffusion factor coefficient, optimum incidence angel and Mach and Reynolds number determined from text and papers. Then obtained a model from experimental data to determine shock loss and extended algorithms to specify critical Mach number and chocking mass flow. With quotation Craig and Cox method we determined a method for calculation optimum values of work and flow coefficient. Finally with use of obtained algorithms, the experimental data's of axial flow compressor of Industrial Sharif University was surveyed and design point mass flow was calculated. Then work and flow coefficient on design point and geometry of axial flow compressor of Industrial Sharif University was studied and showed that these parameters were designed at optimum values.
