Evaporative Cooling: Principles and Applications

This lecture covers the principles and applications of evaporative cooling, focusing on the assumptions, Chilton-Colburn analogy, Reynolds analogy, and the analogy between mass and heat transfer. It also discusses the cooling of a canned drink using wet cloth and air blowing, as well as the calculations involved in determining the final drink temperature. The lecture further explores two-phase flow and heat transfer, including natural convection, film condensation, evaporation, surface tension, and pool boiling. Surface energy, surface tension, and the creation of interfaces between fluids are also explained.
