A number of typical ultrasonic immersion inspections require the transducer radiation to propagate through components with non-planar surfaces. As the complexity of the component’s surface increases in terms of shape and curvature, the effects of the part’s curvature on the transmitted wavefield become difficult, if not impossible, to predict by simple heuristic approaches. The development of accurate transducer beam models that can handle these types of fluid-solid interfaces, therefore, becomes essential.
