Mostafa ghiaasiaan providing a comprehensive introduction to the fundamentals and applications of flow and heat transfer in conventional and miniature systems, this fully enhanced and updated edition covers all the topics essential for graduate courses on twophase flow, boiling, and condensation. The subscripts g and f indicate the vapor and liquid phase at saturation, respectively. In the condensation section, the condensate and the vapor have a heterogeneous flow, which is characterized by intensive turbulence. The book provides a balanced coverage of twophase flow and phase change fundamentals, wellestablished art and science dealing with conventional systems, and the rapidly developing areas of microchannel flow and heat transfer. Flow boiling boiling is called flow boiling in the presence of bulk fluid flow. The proposed research aims to develop an integrated twophase flow boiling condensation facility for the international space station iss to serve as primary platform for obtaining twophase flow and heat transfer data in microgravity. This text is an introduction to gasliquid twophase flow, boiling and condensation for graduate students, professionals, and researchers in mechanical, nuclear, and chemical engineering. Boiling and condensation differ from other forms of convec. Notes on twophase flow, boiling heat transfer, and. Emphasis is given to the co 2 two phase flow patterns, evaporation heat transfer and pressure drop models for co 2 evaporation inside horizontal tubes. Download file twophase flow, boiling, and condensation in conventional and miniature systems ed 2. In flow boiling, the fluid is forced to move in a heated pipe or over a surface by external means such as a pump.
At the beginning of the condensation section, the flow pattern is annular, because in the core the velocity of the vapor is much higher than the velocity of the liquid. Although boiling and condensation exhibit some unique features, they are considered to be forms of convection heat transfer since they involve fluid motion such as the rise of the bubbles to the top and the flow of condensate to the bottom. Twophase flow, boiling, and condensation in conventional. Flow boiling heat transfer and twophase flow of carbon. Flow boiling and condensation experiment fbce for the. This book remedies that problem by covering all the topics essential for a graduate course. The analysis of twophase condensation heat transfer. Subcooled boiling when the temperature of the main body of the liquid is below the saturation temperature.
