Research during the past decade has shown that dispersions of nanoscale particles in conventional heat transfer fluids, called nanofluids, can enhance its thermal conductivity. The convective heat transfer coefficient of this engineered fluid is substantially higher than that of the base fluid. The nanofluid's superior heat transfer capability depends on its thermophysical properties. The authors of this treatise, from their experimental expertise, have presented useful correlations for the thermophysical properties, which are valuable for engineering applications using nanofluids. Performing...
