Abstract
Lorentz Force Velocimetry is a contactless method for the flow rate measurement of electrically conducting fluids. This method is based on the interaction of the fluid flow with the transversal permanent magnetic field. The equal electromagnetic force acts on the fluid and on the magnet system. The flow rate can be determined by measuring of this electromagnetic force. The magnet system has been optimized to achieve maximal sensitivity at a given magnet system weight. The sensitivity was defined as the ratio between the Lorentz force and the magnet system weight. The numerical model was developed using COMSOL Multiphysics. Validation and verification of the numerical model has been performed. The magnet system was optimized using the optimization toolbox in MATLAB.
