Harmonic Balance Method for Turbomachinery Applications [PDF]
, 2019 Harmonic Balance method for non--linear, temporally--periodic incompressible flows is presented in this work. Assumption of a time periodic flow allows us to formulate 2n+1 coupled steady state problems using Fourier series expansion. By solving 2n+1 steady state problems, we obtain a flow field with transient effects.

Assessment of thermal instabilities and oscillations in multifinger heterojunction bipolar transistors through a harmonic-balance-based CAD-oriented dynamic stability analysis technique [PDF]
, 2009 We present a novel analysis of thermal instabilities and oscillations in multifinger heterojunction bipolar transistors (HBTs), based on a harmonic-balance computer-aided-design (CAD)-oriented approach to the dynamic stability assessment.
