The Propagation of the Front of Parametrically Excited Capillary Ripples
The propagation of the capillary ripple front of the surface of a fluid in a periodically oscillating vessel is investigated theoretically and experimentally. The propagation velocity of the parametric instability front is found from the linear theory; it is demonstrated that the nonlinear front propagates with linear velocity. The front of a parameterically excited ripple is obtained in laboratory conditions’ and the dependence of the front velocity on supercriticality is found experimentally.
