Evaporation of liquid under acoustic-vacuum exposure

The theory of optimal control used is based on the Pontryagin maximum principle under the acoustic-vacuum exposure affecting the liquid evaporation process in an experimental container. Evaporation energy consumption for a given liquid mass is taken as an optimality criterion. The physical and mathe...
