... Abstract Steam condensation in the presence of non-condensable gas is a general phenomenon in various industrial applications. It has been broadly investigated by experimental studies and numerical analyses. Previous experimental studies and numerical analyses have focused on single structure...

... Abstract The phenomenon of steam condensation in vertical pipes is common in nuclear power plants. The main method of steam condensation in vertical pipes is film condensation. Generally, the inlet of vertical pipes is steam. After being cooled by the pipe wall, the steam forms a liquid film...

...) models have been proposed. The models can be applied to CFD code by using (i) source terms in the transport equations or (ii) using respective boundary conditions at the Steam Condensation Region (SCR). Previous validation against PPOOLEX and PANDA tests using the source terms approach faced challenges...

..., and the key parameters including the flow patterns and steam core temperature distributions are measured to provide validation data for the numerical results. In aspect of the numerical work, CFD simulation on the steam condensation is conducted. The heat and mass transfer process is simulated through...
