Since the counter current flow limitation (CCFL) of the two-phase flow has an important influence on the safety analysis of the reactor, it is also of great significance to study some characteristics ...

This study investigates countercurrent air-water two-phase flow in vertical pipes with inner diameters of 26 mm and 44 mm and a height of 2000 mm, under controlled conditions to eliminate heat and ...

Countercurrent flow limitations (CCFL) represent a critical safety and operational consideration in pressurised water reactors (PWRs). In these systems, opposing flows of coolant and vapour within ...

In the packed column with a novel internal, which is made of several structured porous passages, gas is divided into two branches which meet liquid in countercurrent and cross-current, respectively, ...

Abstract: For the two-phase flow problem in porous media, many researchers have conducted in-depth studies on the sequential solution format. These studies mainly use topological sorting algorithms to ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
