Dynamical chaos at propagation of finite amplitude waves in water

The experimental study of propagation and interaction of finite amplitude acoustical waves in water is presented. The results are analyzed by traditional methods and by methods of nonlinear dynamics. The phase portraits of the system are reconstructed from the experimental data for the different conditions (values of control parameter), which are then compared with theoretical models. The numerical estimations of chaotic character of the system: correlation dimensions and Lyapunov spectrum are calculated.
