This paper presents an artificial neural network (ANN) based data integration method for a four-path ultrasonic flowmeter to improve its performance under complex flow profiles. Computational fluid dynamics (CFD) has been used to obtain the flow profiles inside a single elbow and an out-plane double-elbow pipeline, respectively, to extract the flow velocities on different individual sound paths and...
This paper presents a systematic investigation of the influence of complex flow profiles on the performance of multipath ultrasonic gas flow meter by using computational fluid dynamics (CFDs) simulation. To guarantee the overall agreement between the CFD predictions and the measurements, the meshing approaches, generation of boundary layers, turbulence models, and wall treatment methods for CFD simulation...
