Numerical Investigation of Ultrasonic Wave Propagation in Tapered Waveguides
Keywords: Ultrasonic measurements, ultrasonic waveguides, 3D modelling, 2D modelling
AbstractUltrasonic transducers are used for in-line, non-intrusive and non-destructive process monitoring of molten metals, liquids and other materials at elevated temperatures. In this case special high temperature waveguides must be used to protect the surface of the transducer from influence of a high temperature. Objective of this work was numerical investigation of ultrasonic wave propagation in tapered waveguides with λ/4 impedance matching layers of finite lateral dimensions.
