Latest Patents

Choi's latest patents include a one-step method for the production of nanofluids. This method involves a system that utilizes nanoparticle-source evaporation and deposition of the evaporant into a base fluid. The base fluid, such as oil or ethylene glycol, is placed in a rotating cylindrical drum equipped with an adjustable heater-boat-evaporator and heat exchanger-cooler apparatus. As the drum rotates, a thin liquid layer forms on the inside surface. An insulated heater-boat-evaporator containing the evaporant material is positioned near the rotating thin liquid layer. The evaporant material is heated, causing it to evaporate and form nanoparticles, which are then absorbed by the liquid film to create nanofluid.
