Texte intégralIn this work, the emphasis is on the development of a computational code for the numerical simulation of waves propagation in transit-time ultrasonic flowmeters. The simulation of an ultrasonic flowmeter is a challenging task. It implies the propagation of high frequency acoustic waves on long distances (greater than 100 wavelengths), through domains with complex geometries and multiples interfaces between solids and moving fluids. The physical phenomena occurring in this type of configurations are various and can have an important impact on the flow measurement accuracy. Therefore, unlike the approaches used until now (based mostly on the ray tracing model), the physical model used here is based on the wave theory. The wave propagation in the fluid part is described by the linearized Euler equations and in the solid part by the equations of linear elasticity. Along fluid-solid interfaces, these two systems of equations are coupled via explicit boundary conditions. In order to minimize the numerical dissipation and dispersion which may appear in these configurations, the numerical method used to solve the propagation problem is the nodal discontinuous Galerkin method. The code is implemented to run on graphical processing units (GPU). The computational code has been validated numerically and experimentally. Then, it is used in five numerical studies investigating several error sources often encountered in practical applications. The results show that by using a GPU-based discontinuous Galerkin method leads to a powerful tool for the simulation of complex configurations in the domain of ultrasonic flow measurement

Ultrasonic flow meter is an important measuring instrument for process control. Geometric reflections of ultrasound in flows cannot explain some specific phenomena occurred in practical V-type installation for large-diameter pipes. For example, the received signal splits into two major tone-burst groups with a large number of small oscillations. This thesis presents a coordinated theoretical and experimental investigation of ultrasound propagation in the flows and surrounding pipe walls. The simulations include signal reconstruction based on generalized ray tracing and finite-element analysis of sound field in flows and pipes. The primary path of ultrasound traveling in the pipe consists of once forward and reflection over the pipe. The secondary path is composed of excess twice reflections across the walls of pipe. Ultrasound from both paths interfere such that signal splits into two groups for large-diameter polyvinylchloride (PVC) pipes. By contrast, the interference is not obvious in metal or pipes of small diameter. Simulated sound field using two-dimensional finite-element analysis indicates the transmitted plane waves are diverging into cylindrical waves if travel distance increases. Therefore, longer durations of small ringing are induced in received signal. Both results achieved by simulations and still water experiments are in very good agreement. The acoustic speed in the flow has a significant influence on the installation of clamp-on flow meter and determination of flow quantity. The cycle number of received signal beyond the threshold changes if the distance between transmitted and received transducers varies. The minimum indicates the best installation distance. This method has been validated to be true no matter what pipe materials and flows.
