A regime map for direct contact condensation
C.K. Chan,C.K.B. Lee +1 more
TL;DR: In this paper, direct contact condensation is studied by injecting steam downward through a pipe and out of the submerged end into a pool of sub-cooled water, and the motion of the steam/water interface is recorded by high-speed movies and systematically classified, based on the injection rate and the pool subcooling.

An investigation of direct condensation of steam jet in subcooled water
TL;DR: In this paper, the authors investigated the direct contact condensation phenomenon, which occurs when steam is injected into the subcooled water, and found that the magnitude of the average condensation heat transfer coefficient depends mainly on the steam mass flux.
