“…In addition, the analysis of the temperature fields in the substrate shows that when modeling the processes of heat and mass transfer in systems such as “heated substrate/liquid drop/environment”, it is necessary to calculate the heat transfer in the heating source. The assumption that the substrate surface temperature is equal to the heater temperature (as in ref ) can lead to errors in modeling evaporation processes (most likely, the calculated evaporation times will be somewhat underestimated).…”

“…The main problem of such storage devices is that no reliable methods have been developed to remove high-density heat fluxes that occur during thermal runaway of lithium-ion batteries. One of the most promising options for solving this problem is the use of drop cooling systems for heat-loaded surfaces. − The main idea of this technology is the formation (by means of spray action) of a fluid flow discrete in time and space to the heating surface, which intensively absorbs heat (Figure ). During the operation of such systems, as a result of the phase transition, the heated surface is rapidly cooled.…”

This paper presents the results of mathematical modeling of the evaporation of a single water drop from the surface of a copper substrate using a new model, which does not require special experiments to close the system of equations and the corresponding boundary conditions with empirical constants. On the basis of the results of mathematical modeling, it was found that convective currents that occur in a small water drop (≤1 mm in diameter) do not significantly affect the characteristics or conditions of heat and mass transfer processes occurring in a liquid drop heated on a copper substrate. The results of numerical simulation showed that during the initial period of droplet heating, the latter undergoes a rapid transformation of the flow field. Five seconds after the beginning of the thermal action, a quasi-stationary regime of flows in the drop sets in. The model is tested on known experimental data. The theoretical analysis of temperatures at the characteristic points of a water drop and the surface on which the drop is located is carried out in ranges of thermal loads quite typical for practice, conditions for transferring heat and water vapor to the environment. According to the results of mathematical modeling, the possibility of using the developed model in the analysis of the state of cooling of surfaces heated to high temperatures, in cases typically used, is substantiated.

“…The frequency of climate extremes and negative climate change trends in recent years have become one of the major threats to global development [ 1 , 2 ]. Rapidly developing industries and the growing material needs of life have been leading to huge emissions of greenhouse gases, which are largely responsible for raising global climate temperatures.…”
