Presentation / Conference Contribution
Magit, K., Hann, D., Hewkandamby, B., & Kisha, W. (2024, August). Slug frequency for a gas-liquid viscous flow in vertical pipes. Paper presented at 10th World Conference on Experimental Heat Transfer, Fluid Mechanics and Thermodynamics, Rhodes Island, Greece

Slug frequency is an important parameter for designing industrial installations with intermittent gas-liquid flows. The literature contains several empirical correlations to predict this parameter, but most studies have focused on air and water, with...

Characterising Horizontal Two-Phase Flows Using Structured-Planar Laser-Induced Fluorescence (S-PLIF) Coupled With Simultaneous Two-Phase PIV (S2P-PIV) (2024)
Presentation / Conference Contribution
Sherif, A. A., Hann, D. B., & Johnson, K. (2024, July). Characterising Horizontal Two-Phase Flows Using Structured-Planar Laser-Induced Fluorescence (S-PLIF) Coupled With Simultaneous Two-Phase PIV (S2P-PIV). Presented at 21st International Symposium on Applications of Laser and Imaging Techniques to Fluid Mechanics, Lisbon, Portugal

Understanding the physics that underpins the behaviors of two-phase flows is immensely useful for a diverse number of industries, including oil and gas, nuclear, and aerospace. Stratified air-liquid two-phase flows are amenable to the application of two...
