Investigation on Numerical Modeling of Water Vapour Condensation
... When water vapor starts to condense, only the noncondensable gas part in the mixture remains in the vicinity of the interface surface. This gas layer acts as an obstacle between vapor and surface, and makes it difficult for the vapor to penetrate and reach the surface. Consequently, the efficiency o ...

Heat exchanger
A heat exchanger is a device used to transfer heat between one or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air.
