Abstract
A Lorentz force flowmeter is a device for the contactless measurement of flow rates in electrically conducting fluids and has a wide variety of potential applications in metallurgy, semiconductor crystal growth and glassmaking. In order to successfully develop Lorentz force flowmeters it is important to answer the following question: Given a magnet system and a velocity field, what is the force acting on the magnet system? The goal of the present work is to analyse the sensitivity of a simplified longitudinal Lorentz force flowmeter in which the magnetic field is produced by a single coil located outside of a circular pipe. We concentrate here our attention on the influence of turbulence on the measurements and we show that velocity fluctuations do not strongly affect the performance of the flowmeter. An illustration of our numerical results is contained in figure 1 where an isocontour of the Lorentz force is presented, highlighting the fact that the longitudinal flowmeter considered samples preferentially the flow in the vicinity of the wall.
