Numerical analysis of direct contact condensation-induced water hammering effect using OpenFOAM in realistic steam pipes

•Temperature/pressure variations in steam pipes are studied using OpenFOAM v.6.•Numerical simulations are performed on steam pipes used in PMK-2 and KEPCO.•The CFD codes are validated with 1D Stefan condensation and evaporation problems.•Simulation results are also compared with experimental ones pr...
