NONLINEAR CAPILLARY-GRAVITY WAVES PRODUCED

The nonlinear capillary-gravity wave produced by a vertically oscillat ing plate, in which the contact-angle model is considered, is studied by use of the Boundary Integral Equation Method (BIEM). The present nu merical experiment shows that the code is robust and efficient for mod eling the generation and propagation of capillary-gravity waves. It is found that the wave heights of stationary periodic nonlinear waves ra diated away from the plate are dependent on the parameters involved in the contact-angle model. The effect of the contact-angle hysteresis a nd the nonlinearity of capillary-gravity waves on the wave profile is discussed in the paper.
