Formation of a Porous Nanoparticle Layer on a Heater Surface Upon the Boiling of a Nanofluid

摘要

A model has been developed for the formation of a porous layer of nanoparticles (nanolayers) on the surface of a heater during the boiling of a nanofluid. From a practical point of view, the properties and the process of the formation of a nanolayer on the heater surface are of interest. Modification of the heating surfaces in power equipment via the formation of a porous layer on them is more promising than the use of a nanofluid as a coolant. The study of the formation of a nanolayer during boiling provides insight into its properties and aids in the study of its effect on heat transfer during boiling and boiling crisis. The main goal of theoretical simulation at this stage is to obtain a calculation expression to calculate the time of the formation of a layer of a certain thickness on the surface.
