ABSTRACT
Condensation and evaporation heat transfer occurs in many engineering applications. Power condensers, boilers, and steam generators are important components in the conventional and nuclear power stations. Condensers are used in the process industry. Evaporators and condensers are also an essential part of the vapor-compression refrigeration cycles. In the design of these condensers and evaporators, proper correlations must be selected to calculate the condensing and boiling side heat transfer coefficients.
