Anne Skeldon’s paper on Faraday patterns appears in J. Fluid Mechanics

hex43The paper “Can weakly nonlinear theory explain Faraday wave patterns near onset?“, co-authored by Anne Skeldon and Alistair Rucklidge (Leeds), has been accepted for publication in the Journal of Fluid Mechanics. The paper presents the first quantitative comparison between weakly nonlinear theory of the full Navier–Stokes equations and (previously published) experimental results for the Faraday problem with multiple frequency forcing. The paper confirms that three-wave interactions sit at the heart of why complex patterns are stablised but also highlight some discrepancies between theory and experiment. These suggest the need for further experimental and theoretical work to fully investigate the issues of pattern bistability and the role of bicritical/tricritical points in determining bifurcation structure.
