Calculation of heat exchange between the metal microdroplet and the vacuum discharge plasma with consideration of bulk discharge layer formation

While in operation cathode spot of vacuum arc spouts plasma jets, liquid metal drops and splashes [1]. Plasma jets velocity comes up to ~10⁶ m/s, liquid metal drops velocity comes up to ~10⁴ m/s. Meanwhile, for many years researches take continued interest to the problem of pure plasma production [2], it is connected with practical application of vacuum discharge in the process of filming during cathode sputtering under vacuum, in case of determination of vacuum breakers critical operation etc.
