...Chul-Hwa Song; Seok Cho; Hyung-Seok Kang The phenomena of direct contact condensation (DCC) of a steam jet submerged in a water pool occur because of the actuation of steam discharging devices in many industrial processes. There are practically two kinds of technical concerns to consider. The first...
