Poster: Faraday Uncaged
Résumé
The advancement in computing resources in the 21st
century has led to the possibility of detailed study of
complex Faraday wave patterns. We present the first
numerical simulations of standing waves generated
by two-frequency oscillation of 10 cm2 silicone fluid
layer of depth 5.5 mm.
Two-frequency parametric vibrations excite two
competing unstable wave modes. These wave modes
superpose to form quasicrystalline structures. Our
DNS results will allow us to analyse the
superposition of the competing wave modes and the role of viscous dissipation.
