Query: Impact of Size and Thermal Gradient on Supercooling of Phase Change
  Materials for Thermal Energy Storage   Phase change material based thermal energy storage has many current and
potential applications in the heating and cooling of buildings, battery and
electronics thermal management, thermal textiles, and dry cooling of power
plants. However, connecting lab scale thermal data obtained on DSC to the
performance of large-scale practical systems has been a major challenge
primarily due to the dependence of supercooling on the size and temperature
gradient of the system. In this work we show how a phase change material's
supercooling behavior can be characterized experimentally using common lab
scale thermal analysis techniques. We then develop a statistics based
theoretical model that uses the lab scale data on small samples to
quantitatively predict the supercooling performance for a general thermal
energy storage application of any size with temperature gradients. Finally, we
validate the modeling methodology by comparing to experimental results for
solid-solid phase change in neopentyl glycol, which shows how the model
successfully predicts the changes in supercooling temperature across a large
range of cooling rates (2 orders of magnitude) and volumes (3 orders of
magnitude). By accounting for thermal gradients, the model avoids ~2x error
incurred by lumped approximations.
