Abstract
The behaviour of an electromagnetic wall velocimeter for non-intrusive measurement of thin film flows is studied both theoretically and experimentally. A solution for the electromagnetic flowmeter equation is presented and evaluated numerically for particular magnetic fields and thin film velocity profiles. Overall transducer behaviour is examined by a parametric study. An experimental apparatus was designed and built to confirm the calculated transducer behaviour. Flow velocity measurements using a multiple electrode prototype transducer were made over a range of Reynolds numbers. The experimental results are in good quantitative agreement with the theory. The wall velocimeter can be designed to provide a robust, non-intrusive measurement of the mean film velocity.
