Heat Transfer Performance Potential with a High-Temperature Phase Change Dispersion

Energies, 2021
Phase change dispersions are useful for isothermal cooling applications. As a result of the phase changes that occur in PCDs, they are expected to have greater storage capacities than those of single-phase heat transfer fluids.
