EVALUATION OF FORCED REFLOODING EXPERIMENTS USING THE FLUT-FDWR-MM (MODIFIED VERSION OF FLUT-FDWR WITH MOVING MESH IN HEAT CONDUCTOR MODEL)
A new version of the FLUT-FDWR code, named FLUT-FDWR-MM, has been developed in KfK in order to reduce an oscillation trend observed in the predictions of the original code. In the new version, a finer mesh moving with the quench front propagation is introduced into the heat conductor model. This version has been tested by means of post-test calculations of various reflooding experiments in both PWR (FEBA/SEFLEX, NEPTUN I and II) and APWR (NEPTUN III) geometries. The parameters R(v) and R(l) of Oseen's relation for interfacial drag between liquid and vapour phases are reoptimised for the new version.
