Quantitative Analysis of the Spraying Kinetics of Charged Particles in a Cooling Unit

Аннотация

Efficient cooling of heat-generating equipment components is a crucial problem for many industrial sectors. This problem is traditionally solved by using liquid sprayers with low cooling efficiency (because of drop recoil). Electric sprayers were proposed for implementation into industry to avoid recoil of fragmented charged drops because of electrical attraction that provided a dense precipitate of drops on a heated conducting surface and further efficient cooling due to liquid evaporation. Fundamental physical laws are used to formulate a mathematical model (in analytical form) and to obtain a practically useful solution to the fragmentation of a test drop by inertial, electric-field, and surface-tension forces. Results of numerical and graphical simulation of this process are given.
