The gas bubbles behavior in variable gravity - Michael Shoikhedbrod - Bog

In the book is represented the computer physical chemistry model of the behavior of the gas bubble, fixed on the surface of solid material in the fluid, that permits to simulate this behavior on the screen of computer, with the precise parameters in each stage of decrease, increase of acceleration of gravity in the conditions of the aircraft¿s overloads and weightlessness. The developed model permits also show the influence of a change in the properties of fluid (surface tension and contact angle) on its behavior: the release of its surface energy and forces, which fix it on the surface of solid material in these conditions. Furthermore, it is illustrated the computer physical model of the directional movement of the gas bubbles along the whole length of the column of fluid using the vibration in the conditions of weightlessness (degassing fluid). The work of these computer programs with the high accuracy was proved during the flight tests on the board of the flying laboratory IL-76K. In the course of tests, was realized the injection of electrolytic gas bubbles into the melt of model solid material using the vibration in the conditions of weightlessness.
