Presenting Three Design Methods for Axial Compressor Blade via Optimization
Improving the efficiency of compressors has been one of the most important goals of researchers over the years. In this paper, three different methods are presented for parameterization and blade optimization of axial flow compressor. All methods consist of flow analysis tool, optimization algorithms, and parametric geometry generation tool, that are different in each approach. Objective functi...
متن کاملEffect of blade profile on the performance characteristics of axial compressor in design condition
The choice of geometrical shape of the blades has a considerable effect on aerodynamic performance and flow characteristics in axial compressors. In this paper, the effects of the blades shape on the aerodynamic design characteristics are investigated based on Streamline Curvature Method (SCM). Initially, the Streamline Curvature Method (SCM) is used for designing a two-stage axial compressor. ...
متن کاملNumerical Investigation of Single Stage of an Axial Flow Compressor for Effects of Blade Aspect Ratio
In present work, a compressor configuration is taken from literature which will be studied for aspect ratio (ratio between length of blade to chord length) influence over performance. Performance in the sense is pressure ratio of compressor. The aspect ratio of the blade is an important parameter and has a strong influence on the performance of axial flow compressor. There are so many literatur...
متن کاملNumerical Simulation of Dynamic Stall Phenomena in Axial Flow Compressor Blade Rows
This article explores the simulation of stall phenomena in axial compressor blade rows. The approach is based on the numerical solution of the compressible, two-dimensional Navier-Stokes equations. The results of both unforced and forced low-speed rotor stall are presented. In unforced cases, substantial ow separation is observed before the maximum pressure rise operating point is reached. Thes...
متن کاملLife Estimate of a Compressor Blade through Fractography
Failure analysis of fractured components provides some information about the causes and conditions of fracture. Fractography is an indispensable part of the failure analysis as it is usually the only means by which the failure mechanism can be established. By using fractography, some information such as component’s life, values of the stress intensity factor and the applied stress can be calcul...
