Numerical modeling and experimental verification of a low fluid flow inductive flowmeter

Abstract

The article discusses modeling procedures to capture the physical and chemical processes present in operational measurement with a high-precision inductive flowmeter. In this context, a theoretical model and a numerical solution are proposed. Exploiting the combined finite element method (FEM) and the finite volume method (FVM), we prepared numerical models of multiple variants of the flowmeter and computed the output voltage on the device's electrodes. The model joins together the magnetic, electric, and current fields; a flow field; and a physical-chemical nonlinear ion model. The results were obtained by means of the FEM/FVM in ANSYS software and verified via experimental testing.The article discusses modeling procedures to capture the physical and chemical processes present in operational measurement with a high-precision inductive flowmeter.
