Аннотация: A comprehensive technique has been developed for direct numerical simulation of a drop and a heated substrate, taking into account liquid evaporation and conjugate heat transfer. Systematic computational studies have been carried out to determine the main mechanisms of heat transfer during an impact of evaporating droplets on a heaПоказать полностьюted substrate. The heat transfer characteristics were determined depending on the equilibrium contact angle and the thermophysical characteristics of the substrate material. It is shown that with an increase in the contact angle in the cases under consideration, the value of the heat transfer coefficient decreases by about 60%. It has been established that with an increase in the thermal conductivity of the substrate material, the temperature fluctuations during interaction with the droplet decrease. © 2022 by Begell House, Inc.
