摘要
Referring to the interaction of superheated steam (practically stagnant) with subcooled water (slowly moving), the results of experimental research are presented and discussed. As predicted in a theoretical investigation, the total thermal power (and consequently the total heat transfer coefficient) does not show an appreciable dependence on the superheated steam temperature; so it can be practically evaluated by means of available correlations for saturated steam conditions. The direct contact condensation heat transfer coefficient is linked to the overall one and is slightly dependent on the degree of steam superheating, which is experimentally confirmed.
