ABSTRACT
This chapter examines the role of entropy and the Second Law of Thermodynamics in selected problems involving phase change heat transfer, particularly with solidification, melting, and film condensation. It is not intended to cover all aspects of multiphase problems, but rather a sample of selected topics in specific areas where entropy and the Second Law have particular importance. Typical applications arise in heat exchangers, multiphase processing in chemical equipment, and so forth. Rosen and coworkers (1999, 2004) have developed methods of exergy analysis for applications to systems like industrial steam process heaters and thermal energy storage systems. This chapter examines the role of entropy and exergy as design tools for developing improvements to such engineering systems, particularly involving phase change and multiphase flows.
