摘要
The present work is an analysis on the ElectroMagnetic Lorentz Force Velocimetry(EM-LFV).This noncontact flow measurement technique is based on evaluating the Lorentz force generated by the interactions of an electrically conducting fluid with a localized magnetic field that is produced by electromagnets.Analytical and numerical calculations were carried out as a continuation of a previous work published by Thess et al.The objective is to establish the behavior of the Lorentz force as a function of the main geometric parameters considered in the studied geometry. Thus we present here the evolution of the Lorentz force induced in a translating cylindrical solid body and the coefficient of sensitivity of the flowmeter thanks to numerical simulations in respect with the main geometrical parameters of the problem.
