Phase Change Heat Transfer covers theory and experiments in heat transfer associated with boiling and condensation. It presents the basics of solid-liquid-vapor phase interactions and methods to measure surface wettability and interfacial tension between liquid and vapor. Exploring the mechanistic details of pool boiling heat transfer, the book gives correlations for prediction of nucleate boiling, critical heat flux, and post-critical heat flux. It describes and analyzes homogeneous and heterogeneous nucleation. The book also discusses both film and dropwise condensation including integral and differential solutions for laminar film condensation. The book is intended for upper-level undergraduate and graduate mechanical, aerospace, and chemical engineering students taking courses in Phase Change Heat Transfer; Boiling and Condensation; Nuclear Reactor Thermal Hydraulics; and Advanced Heat and Mass Transfer. Instructors will be able to utilize a Solutions Manual and Figure Slides for their course.
