The use of POD filtering to study the transition from 2D to 3D in stratified two- phase flow (2018)
Presentation / Conference Contribution
Hann, D. B., Loizou, K., Vasques, J., Tokarev, M. P., & Cherdantsev, A. V. (2018, July). The use of POD filtering to study the transition from 2D to 3D in stratified two- phase flow. Presented at 19th International Symposium on the Application of Laser and Imaging Techniques to Fluid Mechanics, Lisbon, Portugal

The understanding of the velocity profile beneath waves in sheared flow can have implications for the understanding of heat transfer in many applications. In this paper an analysis of the velocity field beneath 2D and 3D waves is performed to underst...

Study of bubbles entrapped into a gas-sheared liquid film (2018)
Journal Article
Hann, D. B., Cherdantsev, A. V., & Azzopardi, B. J. (2018). Study of bubbles entrapped into a gas-sheared liquid film. International Journal of Multiphase Flow, 108, 181-201. https://doi.org/10.1016/j.ijmultiphaseflow.2018.07.001

The surface of a thick liquid film under strong gas shear is covered by large-scale disturbance waves and small-scale ripples. Disruption of these ripples on top of disturbance waves by the gas stream leads to the creation of droplets that are entrai...

Comparison of disturbance wave parameters with flow orientation in vertical annular gas-liquid flows in a small pipe (2018)
Journal Article
Vasques, J., Cherdantsev, A. V., Cherdantsev, M., Isaenkov, S., & Hann, D. B. (in press). Comparison of disturbance wave parameters with flow orientation in vertical annular gas-liquid flows in a small pipe. Experimental Thermal and Fluid Science, 97, https://doi.org/10.1016/j.expthermflusci.2018.03.020

The interfacial wave structure of the liquid film in both upward and downward annular gas-liquid flows in an 11.7 mm pipe were investigated using the Brightness Based Laser Induced Fluorescence technique (BBLIF). Film thickness measurements were carr... Read More about Comparison of disturbance wave parameters with flow orientation in vertical annular gas-liquid flows in a small pipe.
