Obliquely incident ultrasonic wave propagation in a fluid-solid configuration and solid velocity measurements.

Numerical analyses are performed to investigate ultrasonic wave propagation in fluid-solid half-spaces subject to a directional source. This research is particularly concerned with the behavior of refracted waves within fluid mediums and their utility in determining the acoustic velocities of solid materials. The simulations encompass solids with various mechanical parameters and highlight the influence of incident angles on wave propagation.
