Abstract

Abstract: The current research is unclear regarding the sensitivity of the output of a magnetic flowmeter analysis to the fidelity of the simulated flow field. This study evaluates the effects of higher fidelity models on magnetic flowmeter analysis. An eddy viscosity model, second‐moment closure model, and a Large‐Eddy simulation were compared to laboratory velocity profile data 0.67D downstream of a 1.58D elbow at a Reynolds number of 34, 000. The Large‐Eddy simulation results matched the laboratory velocity profile data best. The authors conclude that the fidelity of the flow field model does cause differences in the analysis of the flowmeter voltage output.
