| Processes of heat transfer accomplished by phase change are more complex than simple heat transfer between fluids. A phase change involves the addition or subtraction of considerable quantities of thermal energy at constant or nearly constant temperature.;Vapor condensing on the surface of the cold tubes is an important phenomenon for the air conditioning and refrigeration industry. A thermodynamic study is made and using heat transfer coefficient the rate of condensation is measured for various parameters. Also, a computer program is prepared to give the rate of condensation of water on tubes for different physical quantities of air. |
