Method of calculating GTE gas-thermodynamic parameters with blade row description of an axial multistage compressor

, 2013
A method of calculating the operating performance of a turboshaft gas turbine engine for steady- state conditions has been developed based on a mathematical model with a row- after- row presentation of a multistage axial compressor.

An Evaluation of Passive Wall Treatment with Circumferential Grooves at the Casing of the First and Second Blade Rotor Rows of a High-Performance Multi-Stage Axial Compressor

Aerospace
The internal losses in the tip clearance region strongly influence the compressor performance and its operational range. Previous research proved that passive wall treatments with circumferential grooves in axial compressors effectively increase the ...

Full annulus simulation on a multistage axial-centrifugal combined compressor

Journal of the Global Power and Propulsion Society
Axial-centrifugal combined compressors are widely used in small and medium aero-engines. This study aims to investigate the performance and flow characteristics of a multistage axial-centrifugal compressor using annulus unsteady simulation. The compressor comprises three axial stages and one radial stage, including the inlet and outlet guide vanes. The

The New Performance Calculation Method of Fouled Axial Flow Compressor

, 2020
Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor.

Influence of Regeneration-Induced Mistuning on the Aeroelasticity of Multistage Axial Compressors

AbstractCurrent developments in turbomachinery favor blade designs which are characterized by low damping. The associated reduction of structural damping, however, creates new problems such as higher vibration amplitudes. Therefore, accurate predictions of these vibration amplitudes and of the fatigue life become increasingly important.
