In this work, various non-linear characteristics of the Density-Wave Oscillations and
Ledinegg Instability, in a heated channel under supercritical pressure, are explored. Unlike …

In this paper, the nonlinear stability analysis of supercritical carbon dioxide (SC− CO 2) has
been carried out using a reduced order nodalized model for a single inclined heated …

A study of non-linear stability analysis using co-dimension two (ie, two free parameters
being varied) bifurcations related to pressure drop oscillations (PDO) in a heated channel …

Two-phase flow instability is influenced by many factors. The reported parameter effects on
instability boundary are incomplete and sometimes conflict. Dimensionless numbers are …

Some new phenomena of Ledinegg instability are observed by portraying a complete flow
excursion process via bifurcation analysis and experimental verification. A mathematical …

In a flow boiling thermal-hydraulic system, Density wave oscillations (DWO) and Flow
maldistribution (FMD) are two important instability phenomena. These instabilities can lead …

Abstract A Novel Nodalized Reduced Order Model (NNROM) is developed in this paper to
analyze the linear stability phenomena in a heated channel with supercritical water as a …

This study numerically investigates the impact of external transverse structural vibration on
the nonlinear dynamics of a subcritical thermoacoustic system. A comprehensive analysis is …

Thermally-induced flow instabilities are a critical issue in multi-channel regenerative cooling
systems. In particular, the interactions between Density-Wave Oscillations (DWO) and Flow …

Density wave oscillations (DWO) and flow maldistribution (FMD) are two important
instabilities among others in two-phase flow boiling systems. As both the phenomena can …
