Paper Abstract

Non-collinear ultrasonic wave mixing for nonlinear ultrasonics is used for various NDT&E applications to characterize structure/material state. Experiments are frequently conducted using immersion ultrasonic techniques. In this configuration various wave modes are generated at the fluid-solid interface. We have characterised this scenario experimentally and developed a 2D numerical model to analyse the influence of the interface on the possible second-order interactions of the ultrasonic waves. The model is based on the decomposition of the ultrasonic wave into a superposition of monochromatic plane waves. As these waves propagate through the interface and solid, their nonlinear interaction defines a flow of energy between the different modes. Using the Murnaghan's nonlinear interaction potential, we have studied the efficiency of this energy transfer as a function different geometrical parameters.
