Implementation of a CFD model for wall condensation in the presence of non-condensable gas mixtures
, 2021 In this paper, we discuss a CFD model to predict vapor condensation on walls in the presence of non-condensable gases, with a specific focus on large scale applications, such as accidental flows in a nuclear reactor containment. It is conclusive from the

Modeling of gas radiation heat transfer for the CFD analysis of containment atmosphere mixing
, 2023 During a severe nuclear accident, considerable amounts of steam, non-condensable gases, e.g., H2, CO or CO2, and radioactive aerosols are released into the containment building along with progressing core damage and molten corium concrete interaction. It

Euler-Lagrangian modeling of aerosol transport, deposition and impact of nuclear decay heat
During a severe accident, the flow within the nuclear reactor containment is primarily induced by buoyancy forces and determines the transport of the steam and non-condensable gases as well as the distribution and deposition of the radioactive fission ...
