Abstract: Multiple studies claiming the usefulness of nanofluids for the enhancement of heat transport have been proven ill-founded. Although they have significantly raised thermal conductivities, there is an inerrant increase in viscosity when adding nanoparticles to a liquid. This paper explores areas of research that analyze nanofluid properties that could potiential indicate future applications. A promising direction is using particles that can change their phase in the liquid due to the latent heat of a phase change (solid to liquid) is usually about 2 orders of magnitude higher than the amount of heat likely given under normal circumstance. Properties are explored briefly, and the thermal conductance is measured via the transient hot wire method along with velocity to display possible relationships between measurements.
