Dynamic simulation of once-through steam generator with concentric annuli tube

Annals of Nuclear Energy, 2012
Abstract Based on the conservation equations of mass, energy, and momentum, the mathematical model of once-through steam generator (OTSG) with concentric annuli tube is developed by moving boundary. The heat transfer section of OTSG is divided into three regions: subcooled, nucleate boiling and superheated regions.

Assessment of Dynamic Instability in Once Through Steam Generator

Volume 3: Thermal Hydraulics; Instrumentation and Controls, 2008
Hydrodynamic flow instability in Once Through Steam Generators (OTSG) is one of the important problems in the design and operation of Liquid Metal Fast Breeder Reactors (LMFBRs). Under certain operating conditions, water flow in OTSG is susceptible to instability due to the close coupling between the thermal and hydraulic processes.

Failure Analysis of Once-Through Steam Generator (OTSG) Tube

ASME Open Journal of Engineering, 2023
Abstract The once-through steam generator (OTSG) produces superheated steam using purified feed water. The plant-specific water quality, steam quality, high temperature, and pressure operations lead to the leakage of the OTSG tubes with economic, safety, and environmental consequences.
