Abstract
The report describes the derivation of the corresponding equation and validations on the TOPFLOW condensation experiments (test series K16). The evolution of the cross-sectional averaged void fraction along the pipe were compared with experimental results. In the test K16_118 the condensation of steam was prevailing. The influence of the heat transfer model bubble – liquid (Ranz-Marshall, Hughmark, Tomiyama) was investigated and the influence of the initial bubble size distribution was shown. In the tests K16_140 reevaporation caused by decreasing hydrostatic pressure was found in the experiments and simulated.
Keywords: CFD; two phase flow; bubble population balance; mass transfer
