01
Transient Rear Cavity Vortex Flow in a Spherical Casing Nuclear Reactor Coolant Pump
This study identifies a new large-scale vortex inside the spherical casing, named the rear cavity vortex. Its characteristic frequency is analyzed to support improved efficiency and operational reliability of the NRCP.
02
Energy Characteristics of Transient Rear Cavity Vortex in a Spherical Casing Nuclear Reactor Coolant Pump
Large Eddy Simulation is combined with Proper Orthogonal Decomposition and Turbulent Kinetic Energy analysis to characterize the vortex energy behavior both qualitatively and quantitatively.
03
Enhanced Quantitative Methodology for Energy Loss Analysis and Its Application to Transient Annular Vortex
This work proposes an enhanced methodology for quantifying energy loss in a newly discovered annular vortex, showing that turbulent entropy production dominates local energy dissipation.
04
LES-Based Time-Frequency Characterization of Vortex-Pressure Coupling in an Axial-Flow NRCP Impeller
A 3D-LES and time-frequency coupled analysis reveals pressure pulsation and vortex structure mechanisms, showing how coupling strength decays from impeller inlet to outlet through turbulence evolution.
