ME204: Heat Transfer

Unit 6: Boiling and Condensation   In this final Unit of the course, we will turn our attention back to heat conduction and convection and study their roles in boiling and condensation.  Heat transfer in boiling and condensation is very complex but of considerable technical importance.  You will learn about different boiling regimes (including nucleate boiling, film boiling, and critical heat flux) as well as different condensation modes (including film condensation and dropwise condensation).  You will need to use what you learned in Units 2 and 3 to derive the equations for boiling and condensation heat transfer.

Unit 6 Time Advisory
This unit will take you approximately 28 hours to complete.
