NUMERICAL DESCRIPTION OF ACOUSTIC VIBRATIONS OF A VAPOR–GAS–DROPLET MIXTURE IN A CLOSED CHANNEL BASED ON A ONE-VELOCITY, ONE-TEMPERATURE MODEL

The paper describes a mathematical model and the results of numerical calculations of resonance acoustic vibrations of a vapor–gas–droplet mixture in a closed volume under the action of periodic acoustic waves generated by a harmonically vibrating piston. The numerical method of solving the equations of the model is based on MacCormack′s scheme. The model of equilibrium phase transitions used in the numerical scheme has allowed a chart of regimes of the vapor–gas–droplet mixture vibrations to be constructed depending on the initial vapor content. In accordance with the piston vibration amplitude, the limit of the critical vapor content below which vapor condensation is impossible has been found.
