Abstract: The suspension of small particles from flat surfaces is recognized as a source of pollution and a potential hazard to exposed humans. The interaction of air flow over a particle in contact with a flat surface was studied. ...

Abstract: This study aims to experimentally examine rebounding characteristics of a freefall droplet which impacts on a static droplet with a sphericalcap shape in a low Weber number range. Two wellaligned highspeed cameras were ...

Abstract: To understand the physics behind dropwise condensation, a microscopy technique must be able to measure a sub-nanometer film at a high temporal resolution (>1,000 FPS). In this work, automated Surface Plasmon Resonance ...

Abstract: A surface plasmon resonance (SPR) imaging microscopy coupled to a high-speed camera is used to visualize the frost propagation inside a subcooled liquid droplet. The SPR experimental setup consists of a 50 nm thick gold-coated ...

Abstract: Drop condensation and coalescence is visualized using highspeed Surface Plasmon Resonance (SPR) reflectance microscopy. SPR microscopy is a labelfree technique that can characterize thin films (less than 1آµm) by detecting ...

Abstract: The control of propellant boiloff is essential in longterm space missions. However, a clear understanding of propellant cryogenic condensation/evaporation in microgravity is lacking. One of the key factors in designing ...

Abstract: One of the key limitations to longterm space missions is to avoid propellant boiloff in a microgravity space environment. Even with the use of active and passive controls of propellants, boil off is inevitable. Longterm ...
