N2 - Axisymmetric computational fluid dynamic (CFD) studies have been undertaken for the case of a coaxial, ultrasonic transducer housing in a cylindrical cross-section metering duct and compared to experimental results taken by laser Doppler velocimetry. Results are presented for a meter geometry having a single strut attachment of the transducer housing to the duct wall at Reynolds numbers (based on mean velocity and meter duct diameter) of 750, 3000 and 8000. Good matches between experiment and CFD modelling have been obtained near the duct walls, with some significant departures near the duct centreline, attributed to the limitations of modelling a 3D flow using an axisymmetric model. This CFD modelling is being used to improve the design of similar flow meters.
