Thermal-Hydraulic Analysis of Once-Through Steam Generators. Final Report

摘要

The objective of this project is to provide EPRI with the best currently available estimates of the steady-state local thermal/hydraulic conditions for The Babcock and Wilcox Once-Through Steam Generator (OTSG). The sensitivity of the estimates to correlation uncertainties is also provided. The best estimate analyses and sensitivity studies were carried out using a developmental multi-dimensional computer code, THEDA-1, which solves the nonlinear conservation equations of mass, momentum, and energy using finite-difference techniques. The tube bundle and tube support plates are represented as a porous media with distributed resistance to flow and heat transfer.
