Abstract
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.
