초록정보

Some studies on direct-contact condensation in cocurrent stratified flow of steam and subcooled water were reviewed. Several approaches have been performed to develop the condensation heat transfer coefficient relationship using Lim's data, which were obtained from the cocurrent stratified steam flow on the fairly thick layer of water. The local Nusselt number is correlated in terms of the local water Reynolds and Prandtl numbers as well as the steam Froude number. In addition, a turbulence-centered model, developed by Theofanous, et al.(1976) principally for gas absorption in several geometries, is modified by using calculated interfacial parameters for the turbulent velocity and length scales. A simple correlation of heat transfer coefficient can be suggested by the analogy between heat and momentum transfer through the interface. These approaches result in a fairly good agreement with the data, whereas, the turbulence-centered model is here recommended since it is based on the turbulent properties which may be closely related to the condensation phenomena. The heat transfer coefficient relationship deduced from the turbulence-centered model has forced to be applicable to the prediction of the condensation rate on both the thick and the thin liquid layer.
