The motion of long bubbles in tubes
TL;DR: In this article, the authors provided a partial theory of the indicator bubble commonly used to measure liquid flowrates in capillaries, and showed that the bubble will not rise at all if where ρ is the difference in density between the fluids inside and outside the bubble.
Journal ArticleDOI
Velocity of large drops and bubbles in media of infinite or restricted extent
TL;DR: In this paper, a simple method of calculating the terminal velocity of fluid particles moving in media of either infinite or restricted extent was proposed. But this method was not suitable for the case of liquid drops falling through gaseous media and gave only a rough approximation.

Structure of a heat pipe
TL;DR: In this paper, a structure of a loop-type heat pipe is disclosed in which a heat carrying fluid, preferably a bi-phase non-condensative fluid, circulates in a loop form in itself under its own vapor pressure at a high speed within an elongate pipe so as to repeat vaporization and condensation, thus carrying out a heat transfer.
