Abstract:
The feasibility of Lorentz Force Velocimetry for flow measurement of poorly conducting electrolytes is demonstrated using experimental results on salt water flow exposed to a permanent magnet system. The results provide a linear relationship between the measured Lorentz force and flow velocity, consistent with the theoretical scaling laws. Further measurements are currently being performed on a new experimental setup. The new experiments are aimed at investigating the effect of flow dynamics on the measured force.
