Comparisons of RETRAN and two-velocity two-phase flow models with experimental data
Abstract
Several aspects of two-phase flow models and computer programs associated with steady-state and transient analyses of nuclear steam supply systems were investigated. The areas investigated include: comparisons of homogeneous equilibrium mixture and two-fluid model predictions with experimental data and with each other; numerical solution techniques; comparison of RETRAN predictions with experimental data; application of RETRAN to simple multi-dimensional flows; and derivation of macroscopic balance equations for two-fluid models of two-phase flows. The results of the investigations show the accuracy and ease of application of RETRAN, some of the limitations associated with homogeneous equilibrium mixture models of two-phase flow, and some of the areas in which RETRAN can be improved.
