Abstract
The results of theoretical and experimental investigations revealed a dependence between the parameters of steam condensation process in tubes and channels on the coolant flow pattern: counter flow, forward flow, and cross flow. The loss of total steam pressure in case of counter flow is higher than it is in case of using a forward or cross flow pattern. During condensation, superheated steam retains its superheated state over the entire tube length if the steam quality at the outlet x 1 > 0, and the superheating temperature depends on the coolant flow pattern. A method for calculating the pressure loss to steam temperature ratio as a function of coolant flow pattern is developed, which is confirmed by experimental data. The ratio \(\frac{{kF}} {{cG}} \) or its versions (where c and G are the specific heat capacity and flow rate of coolant) should be regarded as the main parameter in generalizing data.
