Book Description
The objective of this effort is to better understand the physics of evaporation, condensation, and fluid flow as they affect the heat transfer processes in a constrained vapor bubble heat exchanger (CVBHX). This CVBHX consists of a small enclosed container with a square cross section (inside dimensions. 3 x 3 x 40 mm) partially filled with a liquid. The major portion of the liquid is in the corners, which act as arteries. When a temperature difference is applied to the ends of the CVBHX, evaporation occurs at the hot end and condensation at the cold end resulting in a very effective heat transfer device with great potential in space applications. Liquid is returned by capillary flow in the corners. A complete description of the system and the results obtained to date are given in the papers listed. Wayner, Peter C., Jr. and Plawsky, J. L.

Book Description
Two-phase fluid interface occur in many natural environments as well as scientific applications in the form of bubbles and liquid. Although there are many theoretical studies and assumptions, experimental data does not yet exist, upon which the connection among different scales of two-phase interface in turbulent flow can build. Scales for different scenario can vary by thousands, from pipe flow for fluid transport to ocean flow for ships. Moreover, the relationship among different scales are not simply linear nor static. The purpose of this research is to collect sufficient amount of data in two-phase turbulent flow interfaces, to support and build simulations in the future. In order to obtain the data meeting expectations, a vertical water tunnel is set up for observations with six fast-speed cameras from distinct angles. A series of setup including jet arrays, water pumps, and bubble injectors, provide the experimental environments for turbulence and two-phase fluid phenomenon to occur, whereas the six fast-speed cameras capture images from distinct angles and provide data, after which the provided data will be analyzed. The results from analyzes show that the breakage and deformation of bubbles actually do not always occur as expectations and have many other factors which take further considerations, and that experimental results are definitely meaningful and needed to provide valid theories.

Book Description
Advances in Heat Transfer fills the information gap between regularly scheduled journals and university-level textbooks by providing in-depth review articles over a broader scope than in journals or texts. The articles, which serve as a broad review for experts in the field, will also be of great interest to non-specialists who need to keep up-to-date with the results of the latest research. This serial is essential reading for all mechanical, chemical and industrial engineers working in the field of heat transfer, graduate schools or industry. - Provides an overview of review articles on topics of current interest - Bridges the gap between academic researchers and practitioners in industry - A long-running and prestigious series
