Abstract:
1. A method for producing nanofluids comprising: providing a cylindrical drum having an upper section, a lower section and a cylindrical inner surface; filling a portion of the lower section of the drum with a base liquid forming a base liquid pool; providing an evaporant material as a source of nanoparticles; rotating the cylindrical drum at a speed equal to or exceeding the speed required to drag a portion of the liquid in the liquid pool along the circumference of the inner cylindrical surface of the drum creating a rotating liquid film along the inner surface of the drum; positioning the evaporant material in proximity to a portion of the rotating liquid film and heating the evaporant to a temperature sufficient to cause a portion of the evaporant material to evaporate and form nanoparticles, the nanoparticles being incorporated into the rotating liquid film forming a nanofluid; and cooling the formed nanofluid.
