Assessment of the Wall Condensation Heat Transfer Models for the SPACE Code
The SPACE (Safety and Performance Analysis Code) code considers three wall condensation heat transfer models. Default, alternative and temporary models were selected through an extensive literature survey. For a pure steam condensation, the Nusselt’s (1916) and Chato’s (1962) correlations are used to vertical and horizontal geometry, respectively, and Shah’s (1979) correlations is used to consider the turbulent effects. In the presence of non-condensable gases, the Colburn-Hougen’s diffusion model (1934) was used as a default model, a non-iterative condensation model proposed by No and Park (2002) as an alternative model and an empirical model correlated by Vierow and Schrock (1991) as a temporary model. After those models are implemented in the SPACE code, they were assessed for various test conditions. In the present paper the wall condensation heat transfer models were assessed by using Kuhn (1995)’s experiments, which were performed to investigate the film condensation of downward flowing pure steam or mixtures of steam and non-condensable gases inside vertical tubes. The SPACE wall condensation models could simulate the heat transfer coefficients, heat fluxes, wall temperatures and liquid film flow rates quite reasonably for pure steam condensation. The default, alternative and temporary wall condensation models were also assessed and compared for the experimental data in the presence of non-condensable gas.
