Abstract

This thesis presents a model for predicting the forced convective critical heat flux (CHF) for water over a wide range of thermal-hydraulic conditions which might be encountered during normal and accident operations of a light water nuclear reactor. The model is primarily composed from existing steady-state CHF correlations for tubes or tube and rod bundle geometries, and encompasses the following parametric ranges:

0.3 ≤ P (MPa) ≤ 16.0

6.0 ≤ D (mm) ≤ 30.0

100.0 ≤ G (kg/m2s) ≤ 8000.0

-0.30 ≤ X ≤ 1.0

The correlations used as the foundation of this model are the

1) Westinghouse-3

2) Biasi correlation, and the

3) Modified Barnett correlation

The mode 1 presented is comp a red with available data, and the resultant model is illustrated as a 3-D surface in mass flux, quality, and CHF space to represent general CHF behavior.
