Condensation Systems: Heat Transfer & Phase Changes

This lecture covers the importance of condensation in various industrial applications, such as nuclear power plants and refrigeration facilities. It discusses the heat removal process by phase changes, focusing on condensation on vertical surfaces. The lecture delves into the configuration of condensation systems, the growth of annular films, and the heat transfer mechanisms involved. It also explores non-dimensional equations, boundary conditions, and the derivation of axial velocity and temperature profiles. The lecture concludes with discussions on Nusselt's condensation heat exchange coefficient and the accuracy of calculations in different scenarios.
