Self-Propulsion of Boiling Droplets on Thin Heated Oil Films [PDF]
, 2022 We report on the self-propulsion of boiling droplets which, despite their contact with viscous, immiscible oil films, attain high velocities comparable to those of levitating Leidenfrost droplets. Experiments and model reveal that droplet propulsion originates from a coupling between seemingly disparate short and long timescale phenomena due to ...

Direct numerical simulations of mass transfer in square microchannels for liquid-liquid slug flow [PDF]
, 2008 Microreactors for the development of liquid-liquid processes are promising technologies since they are supposed to offer an enhancement of mass transfer compared to conventional devices due to the increase of the surface/volume ratio.

Local heat transfer to an evaporating superhydrophobic droplet [PDF]
International Journal of Heat and Mass Transfer, 2018 Abstract The heat flux distribution beneath a superhydrophobic evaporating droplet has been explored. High speed, high resolution infrared thermography was employed to measure the heat transfer characteristics of the evaporating droplet. Optical imaging and analytical techniques were used the capture droplet dynamics over the course of its ...

Stable magnetic droplet solitons in spin-transfer nanocontacts [PDF]
Nature Nanotechnology, 2014 Magnetic thin films with perpendicular magnetic anisotropy (PMA) have localized excitations that correspond to reversed dynamically precessing magnetic moments, known as magnetic droplet solitons. Fundamentally, these excitations are associated with an attractive interaction between elementary spin-excitations (i.e., magnons) and were predicted to ...
