Stewart, C. W.

The results of thermal-hydraulic simulations of a Combustion Engineering System 80 U-tube steam generator are presented. Both steady-state and transient conditions are considered to compare the results of the Battelle COBRA-IV homogeneous-equilibrium code and a newly developed two-fluid (UVUT) two-phase flow model called COBRA-TF (EPRI). The details of formulating the code input to simulate the primary and secondary flows are discussed. All results presented here must be considered as only a demonstration and not as actual steam generator behavior.
