Abstract: The effect of nanoparticles in an aqueous dispersion (nanofluid) on the critical heat flux (CHF) removed by boiling liquid from a heat-exchange surface has been studied. It is shown that a nanoparticles layer formed on the heated surface in the course of boiling possesses a hierarchical structure. Hydrophilic properties of this layer and its high permeability facilitating the supply of liquid to vapor bubbles lead to an increase in the CHF density.
