Harmonic balance analysis of magnetically coupled two-degree-of-freedom bistable energy harvesters [PDF]

open access: yesScientific Reports, 2022
Because a magnetically coupled two-degree-of-freedom bistable energy harvester (2-DOF MCBEH) shows the rich, complicated nonlinear behaviors caused by its coupled cubic nonlinearities, understanding the dynamics remains challenging.

Harmonic-balance circuit analysis for electro-neural interfaces. [PDF]

open access: yesJ Neural Eng, 2020
AbstractObjectiveAvoidance of the adverse electrochemical reactions at the electrode-electrolyte interface defines the voltage safety window and limits the charge injection capacity (CIC) of an electrode material. For an electrode that is not ideally capacitive, the CIC depends on the waveform of the stimulus.

A New Framework for the Harmonic Balance Method in OpenFOAM

open access: yesMachines, 2022
The Harmonic Balance Method is one of the most commonly employed Reduced Order Models for turbomachinery calculations, since it leverages the signal sparsity in the frequency domain to cast the transient equations into a coupled set of steady-state ones.

Prediction of Transient Pressure Fluctuations within a Low-Pressure Turbine Cascade Using a Lanczos-Filtered Harmonic Balance Method

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2021
Unsteady pressure fluctuations measured by fast-response pressure transducers mounted in a low-pressure turbine cascade are compared to unsteady simulation results. Three differing simulation approaches are considered, one time-integration method and two
