Keywords: Axial compressor, diffusion factor, solidity, inletflow angle, cascade aerodynamics. 1. INTRODUSTION. In an axial flow compressor, air is compressed
of the diffusion factor throughout the compressor is not properly defined. However, the efficiency is less in the later stages due to distortions of the radial velocity
In incompressible flow with constant axial velocity, the Lieblein diffusion factor in Eq. Blade wake downstream of the exit of a compressor blade cascade.
Degree of reaction. • Diffusion factor Axial flow compressors usually consists of a series of stages. Several stages of an axial compressor can be driven by a
Report presenting a simplified limiting-blade-loading parameter for axial-flow-compressor blade elements derived from the application of a separation criterion
progress in turbomachinery computational fluid mechanics, the compressor designer still uses different fied diffusion factor, and re-evaluated the significant.
Furthermore, the use of lift coefficient for the general compressor case of compressible flow with unequal axial velocities at blade-element inlet and outlet presents
