A method of obtaining enhanced heat transfer in a closed loop thermodynamic system is disclosed. A two-component heat transfer fluid comprising a carrier fluid and a plurality of discrete reversible latent energy transition material particles. The fluid slurry is circulated about the loop and the loop is tuned so that a minimum temperature differential exists between the thermal source and sink in order to maximize the latent heat transport by adjustment of the heat transfer fluid flow rate, the rate of thermal energy input into the heat transfer fluid and the rate of cooling of heat transfer fluid.

DETAILED DESCRIPTION To accomplish the foregoing objects, there is provided a method of obtaining enhanced thermal energy transfer between a thermal energy source and a heat transfer fluid in a closed thermodynamic system.
A two component heat transfer fluid is circulated in proximity to the thermal energy source.
The heat transfer fluid includes a carrier fluid and a plurality of discrete particles that undergo a reversible latent energy transition upon transfer of thermal energy thereto.
The fluid is then circulated in proximity to a thermal radiator or energy sink so that thermal energy is removed therefrom.
The system is tuned to a minimum change in temperature between the thermal energy source and the thermal energy sink in order to maximize the latent heat transport by adjusting the heat transfer fluid flow rate, the rate that thermal energy is input into the heat transfer fluid, and the rat at which the heat transfer fluid is cooled.
