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: The present study experimentally investigates the evaporative characteristics for a nanofluid droplet on heated surface.For experiments, the alumina (Al2O3) nanoparticles having a 50 nm average diameter were distributed ...

Abstract: Three different copper surfaces bare, Al2O3 nanocoated, and Polytetrafluoroethylene (PTFE) coated are prepared and tested to examine the effect of wettability on the pool boiling incipience in saturated water at 1 atm. A ...

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: The main objective of this study is to examine the frosting characteristics affected by the surface wettability. Two different copper surfaces – bare and nano structured were prepared for the experiments. Their static ...

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 ...
