Abstract
A model has been developed which can be used to calculate the particle velocity waveforms at arbitrary positions in a solid immersed in a fluid when irradiated by a transmitting transducer, launching a short pulse of a longitudinal wave into the fluid. Mode-converted longitudinal and shear waves are generated at the interface between the solid and the fluid. Calculations performed agree well with the results of experimental measurements using a specially constructed miniature piezoelectric receiving probe. The model constructed has been used to explain the radiation of a transmitting transducer into an immersed solid and it can be used for the optimal design of a transducer and ultrasonic NDT device in immersion mode, that has been widely used for ultrasonic imaging and automatic inspection.
