The Effect of Vane Number in Casing Treatment of an Axial-Flow Compressor

نویسندگان

چکیده

Abstract Improvement of the operating range compressors will help power and energy plant to work more flexibly integrate with other generation systems. The stall, rotating resulting surge are most dominant limiting phenomenon in axial compressor envelop. Several active passive methods have been employed eliminate occurring these phenomena extend compressors’ stable range. Among these, casing treatment is one useful methods. This study aims investigate effect number stationary blades on performance stall margin an through numerical simulation. Casing treatments two different configurations 33.3 53.5% rotor blade tip exposure six numbers vanes, 30, 40, 60, 80, 90, 120, simulated computational fluid dynamics ANSYS software. simulation validated available experimental data. results reveal that a high configuration, highest vanes provides best for compressor. However, low optimum 90 33.3% exposure, can be found proposed procedure based improvement.

Inviscid Compressible Flow in Meridional Plane of an Axial Flow Compressor

In this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. For this purpose the 3-D unsteady Euler equations in cylindrical coordinate are averaged in tangential direction. Therefore, the equations are reduced to a 2-D system. By averaging the tangential component of momentum equation, a blade force will result. Axial and r...
