Recent work on improving general thermal design methods for condensation inside plain, horizontal tubes is presented, summarizing primarily the advances proposed at the Laboratory of Heat and …

Stratified-wavy flow – Increasing the gas velocity in a stratified flow, waves is formed on the interface and travel in the direction of flow. The waves climb up the sides of the tube, leaving thin films of …
