Abstract
In the companion Part 1 paper, the jet breakup model incorporated into the VESUVIUS code was described. Herein, initial verification of the VESUVIUS jet breakup modeling by comparison of calculation results against the PREMIX PM10 and FARO L-14 experimental data is discussed. Predictions of the main experimental parameters, which include steam outlet flow rate and “interaction region” development for the PREMIX test and test vessel pressure and level swell for the FARO test, are shown to be in good agreement with the test data. In addition, the change with time of the jet axial profile and two-dimensional spacial distributions of the jet and coolant, which are not available as experimental data, are discussed in an attempt to further clarify molten jet behavior.
