Experimental investigation of two-phase instability in natural circulation with direct transient local measurement
… customized high-precision mechanisms. Periodic oscillation is captured when the vapor quality at the test section exit is close to zero. A post-processing method is proposed to extract the oscillation cycles and reconstruct the instability behavior in one representative period. An averaging …

Density-Wave Instability Characterization in Boiling Water Reactors under MELLLA+ Domain during ATWS
Density wave oscillations (DWO) are a class of two-phase flow instabilities which can pose significant safety concerns to boiling water reactors (BWR). During an anticipated transient without scram (ATWS) while operating in the proposed extended operating domain MELLLA+, natural circulation …

Gas lift optimization and flow instability
… are three main flow instabilities caused by, the density wave oscillation, the casing heading pressure and the flow perturbation within the two-phase flow regime. Within this investigation of the flow structure, behaviours and instability of two-phase flow have been investigated experimentally …
