Time-domain harmonic balance method for aerodynamic and aeroelastic simulations of turbomachinery flows [PDF]

open access: yes, 2013
A time-domain Harmonic Balance method is applied to simulate the blade row interactions and vibrations of state- of-the-art industrial turbomachinery configurations. The present harmonic balance approach is a time-integration scheme that turns a periodic

Inlet Flow Angle Determination of Transonic Compressor Cascades [PDF]

open access: yesJournal of Turbomachinery, 1991
Tests of transonic compressor cascades require special measuring techniques to determine the inlet flow angle around sonic inlet flow conditions. One of the main requirements for these methods is the ability to adjust the inlet flow angle during the test to a prescribed value.

State-of-Art of Transonic Axial Compressors [PDF]

open access: yes, 2011
Transonic axial flow compressors are today widely used in aircraft engines to obtain maximum pressure ratios per single-stage. High stage pressure ratios are important because they make it possible to reduce the engine weight and size and, therefore, investment and operational costs.
