Nanofluid, a liquid containing choroidal dispersion of nanometer-sized solid particles, enables high-temperature bodies to be cooled more rapidly during quenching than in pure liquid. Drastic rise of the minimum heat flux temperature (TMHF) caused by

When the dry region on the high-temperature wall is cooled down by liquid, the dry region is transformed into wet region as the temperature shifts in a short time. Vigorous boiling occurs during the temperature transition. Especially, it is called th

In nanofluid that is a liquid containing colloidal dispersion of nanometer-sized particles, it is known that the quenching heat transfer characteristics such as TMHF (minimum heat flux temperature) is improved mainly due to modification of the surfac
