报告题目:Interfacial phenomena involved in the manipulation of drops and bubbles
报告摘要:
The
interfacial phenomenon coupled together with multi-phase flow, is a
multi-disciplinary field and widely exists in numerous industrial
processes, such as emulsification, polymer devolatilization, absorption,
flotation, inkjet printing, fermentation, glass manufacture,
electrospray and so on. Drops and bubbles are typical models to
investigate these interfacial phenomena. Thus the drop (bubble) involved
interface manipulation, including the breakup of interface and drop’s
motion on superhydrophobic surface, was investigated. Firstly, the
pinch-off dynamics of both homogenous fluids and heterogeneous
ferrrofluids, unconfined liquid-liquid (liquid-gas) or confined
liquid-liquid systems was investigated by a high-speed camera. And a
dripping-on-substrate (DoS) system was designed to further study the
rapid pinch-off combining the high-speed camera and ultra-high-speed
acquisition device of electric signals. Then the drop manipulation on
superhydrophobic interface was conducted through two distinct
approaches: superhydrophobic coating on a substrate and superhydrophobic
particles enveloping a liquid drop to form “liquid marble”. The
hurdling behavior of liquid drops on superhydrophobic obstacles and
undressing dynamics of liquid marbles on oil films were discussed and
the slope motion of liquid drops and liquid marbles were then compared.
报告人简介:
Ms
Jiang Xiaofeng is a doctor who has just graduated from École Nationale
Supérieure des Industries Chimiques (ENSIC) in France. During her PhD
stage, she has published papers with the first author in journals like Physical Review E, Adv. Mater. Interfaces, Chem. Eng. Sci., Chem. Eng. Res. Des. etc.
Her research interest lies in the interfacial phenomena like interface
pinch-off, drop manipulation through superhydrophobicity, drop
coalescence and drop impact. She will give a talk to introduce her PhD
work.
