The liquid wave characteristics during the transportation of air-water stratified co-current two-phase flow in a horizontal pipe

On gas-liquid intermittent flow in a horizontal pipe: Influence of sub-regime on slug frequency

“…Once these rollwaves touched the top of the pipe, the pseudo-slugs were formed. Hudaya et al (2019) carried out an experimental investigation on different structures, including pseudo-slug flow and roll waves, that exist in transition regions between stratified and slug flows. They quantified the frequency, the velocity, the wave amplitude and the wave length of theses structures and proposed correlations to estimate theses parameters.…”

Analysis of Horizontal Gas-liquid Intermittent Flow Sub-Regimes Transitions: Physical Mechanisms and Flow Maps

“…Strong aeration and even pseudo slugs, as observed by Thaker and Banerjee (2016a), can be encountered in HAS flow. This gradual transition of the elongated bubble/liquid film interface with increasing VSG is analogue to the transition from smooth stratified flow to annular through the wavy regime, studied by several authors (Chen et al, 1997;Hudaya et al, 2019;Wijayanta et al, 2022Wijayanta et al, , 2023. Therefore, the knowledge obtained in this gradual transition can be directly applied in the study of intermittent flows, in particular for the modeling of the liquid film flowing below the elongated bubble.…”

Analisis pengaruh diameter pipa terhadap perubahan sub-regime pola aliran 2 fasa stratified air-udara pada pipa horizontal

“…Penelitian mengenai aliran slug juga mendukung data yang dibutuhkan untuk karakteristik transisi aliran stratified pada kecepatan superfisial liquid yang lebih rendah. Beberapa peneliti terfokus pada parameter tekanan/pressure drop untuk menentukan sub-regime aliran stratified (Al-Dogail & Gajbhiye, 2021;Hudaya et al, 2019;Seo et al, 2021). Dengan metode yang sebelumnya dikemukakan (CECM), seharusnya sub-regime aliran stratified juga dapat ditentukan.…”
