Analytic springback prediction in cylindrical tube bending for helical tube steam generator

Overview of Steam Generator Tube-Inspection Technology

Degradation of steam generator (SG) tubing due to both mechanical and corrosion modes has resulted in extensive repairs and replacement of SGs around the world. The variety of degradation modes challenges the integrity of SG tubing and, therefore, the stations’ reliability. Inspection and monitoring aimed at timely detection and characterization of the degradation is a key element for ensuring ...

Springback prediction of titanium tube bending considering Bauschinger effect and Young's modulus variation

Investigation on Turbulent Nanofluid Flow in Helical Tube in Tube Heat Exchangers

In this study, the thermal characteristics of turbulent nanofluid flow in a helical tube in the tube heat exchanger (HTTHE) were assessed numerically through computational fluid dynamics (CFD) simulation. The findings of both the turbulent models: realizable k-epsion (k-ε) and re-normalisation group (RNG) k-epsilon were compared. The temperature distribution contours show that realizable and RN...

Development of a Robust Model-Based Water Level Controller for U-Tube Steam Generator

Government or any agency thereof. The views and opinions of authors expressed herein do not necessarily state or reflect those of the United States Government or any agency thereof. SUMMARY Poor control of steam generator water level of a nuclear power plant may lead to frequent nuclear reactor shutdowns. These shutdowns are more common at low power where the plant exhibits strong non-minimum p...

Numerical Simulation of Heat Transfer in a Vertical Inverted U–Tube Steam Generator

In this paper, a numerical scheme has been developed for primary and secondary fluids adopting Euler–Cauchy method to find the temperature distribution of the primary fluid relative to the secondary fluid and vice–versa and to obtain an optimum boiling length of the tube in the vertical inverted U–tube steam generator (UTSG).
