Heat Transfer Engineering

Chapter 11: Boiling and condensation

Abstract

Two-phase heat transfer, which involves conversion of liquid into vapor, referred to as boiling, or conversion of vapor into liquid, referred to as condensation, takes place in equipment such as boilers and condensers in thermal power plants, evaporators and condensers in refrigeration systems, water-cooled nuclear reactors, major equipment in the process industry, and modern heat sinks for thermal management of electronics. Of particular importance in the design of the equipment are the rates of heat transfer or heat transfer coefficients and the associated pressure losses. In boiling and condensation, the coupling between the fluid dynamic process and the heat transfer process is stronger than what ...
