The possibility of hydrogen combustion in reactor containments during accident conditions is one of the important safety issues. Experimental studies in the past have indicated that the steam condensation plays an important role in the hydrogen mixing and distribution in the containment. Computational Fluid Dynamics (CFD) simulations are necessary for accurate predictions. However commercial CFD codes do not have in-built condensation models. A condensation model has been developed and implemented in FLUENT computer code through user defined functions. The developed model has been benchmarked against a channel type geometry and ISP-47 test of TOSQAN test facility.
