The analysis of the existing results of studies on the process of heat and mass transfer, during the evaporation of different model liquids under conditions of ultrasonic exposure and reduced pressure, was carried out. Main results state that the best performances are obtained from kerosene, in terms of evaporation rate, but it is necessary more investigation in order to show a clear dependence on the characteristics of both the ultrasonic waves, namely frequency and amplitude, and the model liquids. The results from the mathematical modeling of the process of evaporation of a model liquid were obtained in the form of temperature variation of the liquid, at different frequencies of the acoustic waves (22 kHz, 30 kHz, 37 kHz) and at an amplitude of the oscillations of the bottom of the bath of 2 µm. Both program and methodology for conducting experiments on the evaporation of a liquid, under reduced pressure and at different frequencies of acoustic waves, have been developed. The initial data, variable parameters, assumptions and limitations for conducting experiments were determined. Piezoceramic emitters were used as emitters of ultrasonic waves, with the same frequencies of the acoustic wave and amplitude of the oscillations of the bottom of the bath used in the mathematical model.

A method is proposed for assessing the results of adjustment maneuvers for a nanosatellite (NS) with an electrothermal propulsion system (ETPS). Using the example of the SamSat-M nanosatellite under development, common causes of maneuvering errors associated with deviations in the manufacturing of the propulsion system are revealed. Probabalistic analysis of the NS maneuvering process was carried out. The design parameters of the ETPS are considered as random factors. Statistical models of the distributions of all random factors are assumed to be equally probable, which is the worst-case scenario, since the true distributions of the design parameters of the ETPS are unknown. The methodological basis of the study is the method of statistical modeling (Monte Carlo method) followed by the use of regression and factor analysis, on the basis of which the influence of the scatter of each of the design parameters on the controlled parameters is determined. Requirements for the design parameters of the ETPS that affect the spread of the projections of the velocity growth vector of the NS and the arising angular motion have been formulated. The presented results can be used to assess the influence of production deviations in the design parameters of propulsion systems on the nature of spacecraft motion, as well as to state requirements for the spread of design parameters to ensure the achievement of the objective.
