Numerical Analysis of the Condensation Characteristics of Different Heat-Transfer Media in an Air-Cooled Condenser1

Resumo

Amathematical model of an air-cooled condenser (ACC) section is developed. It allows comprehensive study of its operation for various geometries, conditions, and heat-transfer media. Asoftware program for numerical analysis of an ACC section developed using Excel spreadsheet software is used to study the dependence of rates, thermal and aerodynamic characteristics of the condensation of a number of heat-transfer media in a standard ACC section on the velocity of the cooling air. The model can be used for design of thermal power plants and refrigerating machines with air-cooled condensers.
