6. Improved modeling of ultrasonic systems : feasible for industrial applications
Abstract : In this thesis tree aspects of ultrasonic measurement and modelling techniques have been investigated. Namely, transducer diffraction modelling using equivalent circuits, wave propagation in multi phase flow, and wave propagation in gases. The work is relevant both from an scientific point of view and from an engineering point of view. READ MORE
