Modeling of Multi-Component Fuel Vaporization for Spray Simulations Using Continuous Thermodynamics
A preliminary study on drop-bubble dynamics and instability with Marangoni effects is also given. This issue is motivated by its potential application for improving air-fuel mixing and understanding the possible drop-bubble breakup mechanism.

Intensification of Gas Absorption in a Downward Flow Microbubble Bioreactor
… at ambient pressure into a downward microbubble flow. The performance of this device exceeds known technology in terms of volumetric gas transfer energy efficiency defined as reactor divided by reactor power density (achieving values near 0.34 s<sup>-1</sup> m<sup>3</sup> kW<sup>-1</sup>) …

Experimental study and characterization of bubble behaviors in the orifice-induced hydrodynamic cavitation
… of orifice-induced cavitation and transitional bubble behaviors. The transition from non-cavitation to fully developed cavitation was carefully studied. Cavitation bubble clouds were observed at orifice, indicating the inception of cavitation. The number of bubbles produced were dramatically …

Computations of bubble dynamics with heat transfer
… the heat transfer enhancement caused by air bubble motion is of practical interest in many industrial applications ranging from boiling solar collectors to nuclear reactors. A bubble sliding over a heated obstacle increases heat transfer by displacing liquid, particularly in the wake region …

Moving contact lines, wetting transitions and interfacial instabilities in confined environments
… and methane venting from seafloor sediments to bubble/drop/emulsion generation in microfluidic techniques. All these flows are inherently multi-scale, from the intermolecular interactions on the nanometer scale in the vicinity of contact lines, where fluid phases meet the surrounding solid …
