| Abstract: | This paper is concerned with the analysis of motion of a gas bubble in a uniformly oscillating incompressible fluid. A theoretical
model explaining the effect of sinking of gas bubbles in the absence of a standing pressure wave is validated experimentally.
The conditions under which this effect occurs are determined, and a simple formula is derived for the average velocity of
a gas bubble in the fluid. |
