EXPERIMENTAL STUDY OF A STATIC PUMP BASED ON A MAGNETO-THERMAL COUPLING IN FERROFLUIDS

The cooling liquid of electronic devices is generally made using a mechanical pump which reduces the overall performances of the system and its reliability. It has already been shown that ferrofluids with low Curie temperature are able to create the liquid flow without any mechanical part. In fact a pressure gradient can be obtained when subjecting this ferrofluids to both a temperature gradient and a magnetic field. This paper proposes a novel experimental setup in order to measure this pressure gradient. Steady state and transient results are then discussed.
