Rewetting of hot vertical tubes by a falling liquid film with different directions of venting the generated steam

An experimental study of quenching of a hot vertical tube by sudden introduction of a falling liquid film was investigated under different methods of venting the generated steam. The steam generated during the quenching process may form a countercurrent vapor velocity which exceeds the onset of flooding limit causing flooding of the liquid film and resisting the propagation of the quench front delaying the rewetting process. To study the effect …
