Study of two-phase flow instabilities began in the late 1920′ s, and in the nearly 100 years
since, significant progress has been made in both experimental and theoretical …

An updated review of two-phase flow instabilities including experimental and analytical
results regarding density-wave and pressure-drop oscillations, as well as Ledinegg …

The flow instability phenomenon within parallel helical tubes is experimentally studied. The
oscillation characteristics of wall temperature are comprehensively discussed. In the …

High heat flux and good axial temperature uniformity of channel flow boiling demonstrate
that it is ideally suited for next-generation cooling systems. Such systems, however, are …

This paper reports on the advancement in the study of thermal-hydraulic dynamic
instabilities with reference to the helical-coiled tube geometry. A full-scale open-loop …

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

Abstract High Temperature Gas-cooled Reactors (HTGR) have the advantage of inherent
safety compared with most Gen III reactors. They also have very high temperature, which …

Several design basis accidents such as loss of coolant accident (LOCA) and main steam
line break (MSLB) of pressurized light water reactor could threaten the integrity of …

Once-through steam generators with helically-coiled tubes (OTSG-HC) are susceptible to
density wave instability phenomena. In order to investigate the stability performance of the …

Two-phase flow instability, inherently accompanied by hydraulic and thermal oscillations, is
a complex phenomenon that must be overcome to design an efficient flow boiling heat …
