A Fundamental Study of Gas and Vapor Bubble Dynamics in Micro-Channels

Abstract

The aim of this project was to carry out a fundamental study of the basic: Physics underlying the applications of gas and vapor bubbles in heat transfer systems, pumps, actuators, and other small-scale systems. Since these applications require a detailed understanding of the physics of bubbles in tightly condensed spaces, such as micro channels, a large fraction of the effort has been devoted to this type of problem. Some new pumping principles have also been discovered and a patent application filed on July 6, 1999. A response to the Patent Officer comments was sent on May 2000.
