... model allowing for the Brownian diffusion behavior of the mixing gas under the presence of non-condensable gas. Compared with the COPAIN test data and simulation results from the GASFLOW code obtained from previous literature, the applicability and prediction error of the present model are evaluated...

Proc. ASME. ICONE29, Volume 15: Student Paper Competition, V015T16A075, August 8–12, 2022
Publisher: American Society of Mechanical Engineers
Paper No: ICONE29-92081
... 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...

... in the heat and mass transfer analogy model. Via boundary layer study of species concentration and energy balance, the non-condensable gas effect on condensation is added into the equation. For the condensation heat transfer coefficient of turbulent vapor flow associated with laminar condensate, numerical...

... with non-condensable gas injection, where helium was used to simulate hydrogen effect on the IC. The reaching distance of steam in the heat transfer tube was estimated by observing the region where nucleate boiling occurred on the outer surface of the heat transfer tube, and the heat transfer coefficient...
