Lorentz Force Velocimetry (LFV) is a noncontact method for flow measurement in electrically conducting fluids, especially in high temperature, opaque, and aggressive molten metals. The objective of this paper is to explore the application of LFV for open channel liquid metal flows by numerically establishing the relationship between the measured Lorentz force and the flow rate, thereby providing calibration criteria for LFV. The methodology first involves investigating a metal bar with varying cross-section shapes as it passes through a magnetic system. This is followed by an exploration of the relationship using a multiphysics numerical model that fully couples the Navier-Stokes equations with Maxwell's equations. Results indicate that the numerical model possesses the capability to compute calibration factors for various open channel flow cross-section shapes, facilitating accurate flow measurement. Future work may expand on transient simulations pertaining to free surface deformation, optimization of the magnetic field, and more intricate characteristics of realistic open channel flows.
