Subharmonic parametric instability in nearly brimful circular cylinders: a weakly nonlinear analysis

A Bongarzone, F Viola, S Camarri… - Journal of Fluid …, 2022 - cambridge.org
In labscale Faraday experiments, meniscus waves respond harmonically to small-amplitude
forcing without threshold, hence potentially cloaking the instability onset of parametric …

A revised gap-averaged Floquet analysis of Faraday waves in Hele-Shaw cells

A Bongarzone, B Jouron, F Viola… - Journal of Fluid …, 2023 - cambridge.org
Existing theoretical analyses of Faraday waves in Hele-Shaw cells rely on the Darcy
