Abstract:

Under the present three-year ONR grant, research has been actively pursued by Dr. Wus group in the general field of nonlinear waves, vortex dynamics and hydrodynamic stability theory with the following scientific objectives and goals Nonlinear waves under resonant forcing, Hydrodynamic stability theory for forced nonlinear waves Forced production of nonlinear vortex waves, Forced emission of solitary waves in shallow water Stability of the solitary waves forcibly generated, Forced nonlinear waves in a channel with variable cross section and nonlinear vortex waves in stratified and rotating fluids
