There is a need in thermo-fluidic disciplines to measure
temperature distributions in flowing liquids, for
example to investigate heat transfer for performance
improvement of devices. Although primarily used for
medical applications, MR thermometry (MRT) has the
potential to provide these measurements. This work
applied MRT to investigate temperature distributions in
a heat exchanger using different flow rates,
demonstrating that MRT can provide high-quality 3D
measurements of temperature fields in such setups.
Collaboration with thermo-fluidic engineers can also
benefit the medical community, for example through the
investigation into MR compatible materials that could be
used in medical devices.
