ME-446 / 3 credits

Teacher: Lu Zhengmao

Language: English


Summary

This course covers the fundamental and practical analysis of liquid-gas interfacial heat and mass transfer in various contexts including power generation, water purification, and cooling. Students will learn about the multiscale physics involved in evaporation, boiling, and condensation.

Content

1. Introduction to liquid-gas interfacial transport phenomena
2. Capillarity and wetting
3. Evaporation physics (diffusion-based model, kinetic theory treatment)
4. Boiling (onset of nucleation, nucleate boiling, critical heat flux, flow boiling)
5. Hydrogen production (bubbles from gas evolution reactions)
6. Condensation (filmwise, dropwise, jumping droplet)

 

Keywords

Interfacial phenomena, evaporation, boiling, hydrogen production, condensation, heat and mass transfer

Learning Prerequisites

Required courses
