Extension of theoretically based DNB prediction to high void fraction, intermediate mass flow rate, and rod bundles

Thesis/Dissertation ·
OSTI ID:5500744
The present work extends a theoretically based DNB predictive procedure so that it is applicable at high void fractions and low velocities. This theoretically based DNB predictive procedure was originally developed for round tubes by Weisman and Pei and in its original range of applicability, is as accurate as most empirical correlations. Highly favorable comparisons of the present extension with experimental data were obtained. The present work also develops a procedure for applying this DNB prediction procedure to rod bundles. The results of this study show that application of this theoretically based DNB prediction procedure to rod bundles with and without mixing vane grids leads to good agreement with experimental observations.
