Description

This lecture covers the physics of evaporation and boiling, explaining the differences between the two processes. It delves into the concept of pool boiling, discussing the regimes of pool boiling and the terminologies associated with boiling heat transfer. The instructor explores the latent heat and sensible heat involved in phase change, emphasizing the efficiency of phase change processes. Various regimes of pool boiling, such as natural convection, onset of nucleate boiling, and nucleate boiling with isolated bubbles and slugs, are discussed. The lecture also touches on critical heat flux and transition boiling, highlighting the significance of these phenomena in thermal system design.
