Non-Uniform Time Sampling for Multiple-Frequency Harmonic Balance Computations [PDF]

, 2013
A time-domain harmonic balance method for the analysis of almost-periodic (multi-harmonics) flows is presented. This method relies on Fourier analysis to derive an efficient alternative to classical time marching schemes for such flows.

Performance and Stall Margin Evaluation of Axial Slot Casing Treatment in a Transonic Multistage Compressor

Aerospace
Adverse pressure gradients are intrinsic to compressor flow behavior and are further intensified by secondary effects associated with rotor tip clearance flow interactions. Tip clearance generates leakage flow, which leads to the formation of tip leakage
