Abstract
The study of the dynamic behavior of gas bubbles in a fluid and the control of their behavior in a fluid under conditions close to weightlessness, using vibration effects, are important for solving several technological problems related to the needs of space technology (degassing of special fluids and fuel). The author, in a previously published article, considering vibration effects on air bubbles in an incompressible, non-viscous liquid located in a flat rigid vessel under conditions of variable gravity, obtained the conditions for the floating, sinking and oscillation of air bubbles around the equilibrium level in a fluid and the equilibrium level equation itself. In this article, the obtained equilibrium level equation was algorithmized, written in Turbo Basic computer language codes and compiled into an executable file. The result of the work of the obtained exe file was a numerical determination of the equilibrium level, around which the "swarm" of air bubbles oscillates, according to the corresponding vibration frequency at a given vibration acceleration, the volume of the "swarm" of air bubbles and the g-factor (an indicator of acceleration of gravity). For simulation on the screen of a personal computer, the movement of an air bubble or a "swarm" of air bubbles in an oscillating liquid in accordance with the calculated pairs, equilibrium levels and the corresponding vibration frequencies under conditions of a changing value of the g-factor (an indicator of acceleration of gravity) on the flying laboratory, an animation program was created, executed in the computer language Turbo C. The developed program allows synchronous modeling of the aircraft's trajectory (flying laboratory) when changing the value of the g-factor and the movement of an air bubble or a "swarm" of air bubbles when changing the vibration frequency in microgravity conditions. The flight tests conducted on board the IL-76K flying laboratory fully experimentally confirmed the theoretically obtained results.
