A general theory of moving contact lines with phase change general theory of moving contact lines with phase change
Pierre Colinet and Alexey Rednikov
Prof. Dr. Ir Pierre Colinet
FNRS Senior Research Associate
Université Libre de Bruxelles
Laboratory TIPs (Transfers, Interfaces and Processes)
50, av. F.D. Roosevelt, C.P.165/67, B-1050 Brussels, Belgium
Email : pcolinet@ulb.ac.be
Prof. Pierre Colinet was graduated from Université Libre de Bruxelles, where he received his PhD in 1997. He was then granted a 2-years Individual Marie Curie post-doctoral fellowship in Universidad Complutense de Madrid. From 1999 to 2003, he benefited from a post-doctoral researcher position funded by the FNRS (Belgian National Research Fund) in Université Libre de Bruxelles, and was nominated as a permanent Research Associate of the FNRS in 2003. In 2008, he became Director of the Fluid Physics Unit, one of the two Research Units of the Laboratory TIPs (Transfers, Interfaces and Processes), and was recently nominated FNRS Senior Research Associate in 2011. Currently, Prof. Colinet teaches Physical Chemistry, Nonlinear Dynamics, and Modeling of Multiphase Systems. He has published 2 books, co-edited 3 books, and co-authored 51 papers or book chapters, and about 40 conference proceedings.
His main research interests are Fluid Dynamics (interfacial flows, natural convection, microgravity fluid mechanics, bubbles, drops, films, spreading and wetting, contact lines), Transport Phenomena (phase change, heat transfer, modeling of industrial processes such as CO2 absorption, thin-film evaporators), Nonlinear Physics (self-organized patterns and waves, defects, transitions to chaos and turbulence, generic aspects of evolution equations, noise-affected phenomena) and Thermodynamics (physical chemistry of interfaces, statistical thermodynamics, phase transitions, irreversible processes).
Abstract
Far from claiming any ultimate resolution of the contact line paradoxes, we argue that a somewhat controversial paradigm, originally employed by de Gennes and collaborators, actually appears both to be quite reasonable at its foundations and to lead to physically consistent final results in a wide variety of situations. Curiously enough, while containing a singularity in itself, the approach nonetheless renders the classical contact-line singularities – both hydrodynamic and thermal – integrable, in particular as far as several quantities of interest are concerned. It is also readily applicable to quite a few situations: from equilibrium shapes and moving contact lines of a non-volatile liquid, to cases with evaporation into either a pure-vapor or an inert-gas atmosphere. The paradigm actually consists in an approach involving both the (positive or negative) spreading coefficient and the disjoining pressure in the form of a positive inverse cubic law, a conceptual framework that most notably describes structures with truncated precursor films on a macroscopically bare solid surface.

Dr. Michael Dreyer is a professor in the Department of Mechanical Engineering at the University of Bremen. He is leading the fluid mechanics and multiphase flow group at the Center of Applied Space Technology and Microgravity (Chair of mechanics and fluid mechanics, space technology and microgravity). His research is dedicated to the understanding of non-isothermal multiphase flows in different acceleration environments. Differing accelerations up to fully compensated gravity can be found in spacecrafts and rockets, and lead to unique flow phenomena different from terrestrial observations. He is the chairman of a French-German project on the behavior of propellants in launcher tanks. His research is mainly funded by the German Aerospace Center DLR and the European Space Agency ESA. He is the principal investigator on the NASA-DLR experiment CCF which is operating on the International Space Station since January 2011. Dr. Dreyer is the editor-in-chief of the Springer Journal Microgravity Science and Technology. He has published 2 books and co-authored 61 papers in peer-reviewed scientific journals.

Haruhiko Ohta is a professor of Dept. Aeronautics and Astronautics in Kyushu University. He started research on boiling heat transfer when he was a student, and obtained degree of Dr. Eng. from Kyushu University in 1981. He investigated the effects of pressure, surface roughness, surface orientation and mixture concentration on nucleate boiling. From 1990 to 1991 he visited the laboratory of Prof. Straub in Technical University of Munich, and started new investigation on microgravity boiling and two-phase flow. He joined in many projects for microgravity flight experiments as a principal investigator, and clarified, for example, the effect of gravity on two-phase forced convection by using transparent heated tubes he developed. After he became a professor in 1999, he reinforced the collaboration with Japanese space agency and started the development of two-phase loops and cold plates for the thermal management system in space platforms. Recently, he concentrates on the development of high-performance cooling systems for large electronic devices operating at extremely high heat flux. Through the collaborating development with an auto company in Japan, the technology is to be reflected in the cooling system of inverters for hybrid vehicles of the next generation.

Non-linear thermocapillary convection in half-zone liquid bridge - on-orbit experiments on Kibo aboard the ISS
Ueno, I., Nishino, K., Kawamura, H., Ohnishi, M. & Matsumoto, S.
The long-duration fluid physics experiments have been carried out at "Kibo", the Japanese experiment module, aboard the International Space Station (ISS) since 2008. In these experiments, various aspects of thermocapillary convection in a half-zone (HZ) liquid bridge are examined. This series of experiments enable us to conduct lots of experiments that are impossible to run on Earth because of the gravity, and have been providing numbers of invaluable results. In 2010, thermocapillary convection in a HZ liquid bridge of 50 mm in diameter and 10-cSt silicone oil had been examined. During this term of experiment, the authors put a large temperature difference ΔT between the two rods, and succeeded to generate nonlinear convection fields in a HZ liquid bridge at three kinds of aspect ratios Γ = H/R, where H is the liquid bridge height and R the liquid bridge radius. The hydrothermal wave (HTW) proposed by Smith & Davis (JFM, 1983) is observed. We largely pay our attention to the behavior of the HTWs, and analyze the chaotic behavior of the surface temperature variation. We will introduce the chaotic thermocapillary convections and their transition scenario in the HZ liquid bridge.

Precursor film in electrowetting and precursor chain in wetting of an interior corner for nano droplets

Abstract
Molecular dynamics (MD) simulations and molecular kinetic theory (MKT) analysis are performed to explore the formation of the precursor film (PF) in electrowetting [1] and precursor chain (PC) in the wetting of an interior corner for nano droplets, the latter is studied for the first time. A comparison is made among the PF, the PC and the single file chain in carbon nanotube [2]. It is found that the disjoining pressure converged at the interior corner is the driving force for the formation of the PC, and the PC could eliminate the pressure and energy singularities at the interior corner. The new findings in this talk would assist in the understanding of the multi-scale droplet dynamics under multi-physical-chemical fields [3].
