Performance Evaluation Of Axial Flow Compressor Using Stages Characteristics

Abstract

The performance characteristics of axial flow compressors due to variation in size of blade, pressure, temperature and shaft rotational speed determined the output variables such as work output and efficiency. The performance depends upon the blade diameter, mass flow rate, density of the flowing fluid, stage pressure ratio, stage delivering pressure and temperature. This paper focus on how parameters obtained from each stage, influence the Performance of the axial compressor. These various parameters that has influence on the performance of the compressor were analyzed with tables and graphs, to show clearly their inputs to the compressor performance. For the axial compressor to deliver compressed air to the combustor for onward delivery to the turbine, each stage should be able to attained a better performance that is better than the preceding stage. This work also focus on how energy is exchange between the blades and the moving fluid (compressed air) and variation of flow over the blades.
