How do the liquid properties affect the entrapment of bubbles in gas sheared liquid flows? (2021)
Journal Article

A large number of industries use fossil fuels for the purpose of cooling and lubrication utilizing a gas stream that acts as a shearing force on the liquid surface. Decreasing the carbon footprint of these processes needs an improved understanding of... Read More about How do the liquid properties affect the entrapment of bubbles in gas sheared liquid flows?.

Asymmetrically heated multi-stage travelling-wave thermoacoustic electricity generator (2021)
Journal Article

Recent developments of thermoacoustic engines have demonstrated that thermoacoustic technology is a viable option for waste heat recovery and low-cost electricity generation, Thermoacoustic technology is capable of converting low-grade heat to electr...

Study of bubbles entrapped into a gas-sheared liquid film (2018)
Journal Article

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

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.

Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling (2017)
Journal Article

Melt ejection is the dominant material removal mechanism in long, ms, pulse laser drilling of metals, a process with applications such as the drilling of cooling holes in turbine blades. Droplets of molten material are ejected through the entrance ho... Read More about Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling.

Study of the impacts of droplets deposited from the gas core onto a gas-sheared liquid film (2016)
Journal Article

The results of an experimental study on droplet impactions in the flow of a gas-sheared liquid film are presented. In contrast to most similar studies, the impacting droplets were entrained from film surface by the gas stream. The measurements provid...

A study of droplet impact on static films using the BB-LIF technique (2016)
Journal Article

This paper presents results of single droplet impacts on films of different height taken using the Brightness Based Laser Induced Fluorescence technique (BB-LIF). The dynamics of drop impingement such as the shape of the cavity, residual film thickne... Read More about A study of droplet impact on static films using the BB-LIF technique.

Study of gas-sheared liquid film in horizontal rectangular duct using high-speed LIF technique: Three-dimensional wavy structure and its relation to liquid entrainment (2014)
Journal Article

© 2014 The Authors. The flow of a liquid film sheared by high velocity gas stream in a horizontal rectangular duct was investigated using a high-speed laser-induced fluorescence technique. Measurements of local film thickness were resolved in both lo...
