Chaotic motion of microplugs under high-frequency thermocapillary actuation
This paper reports experimental results on chaotic motion of liquid plugs under high-frequency thermocapillary actuation. In the experiments, two heaters were alternately activated. The liquid plug was positioned in a glass ...
Thermocapillary actuation of a water droplet encapsulated in an oil plug
This paper reports the theoretical and experimental results of thermocapillary actuation of silicon oil plugs with encapsulated water droplet inside a capillary tube. The paper first describes the analytical models for ...
Generation of shock-free pressure waves in shaped resonators by boundary driving
Investigation of high amplitude pressure oscillations generated by boundary driving in shaped resonators has been carried out both theoretically and experimentally. In the theoretical modeling, the acoustic resonance in ...
Thermocapillary actuation of liquid plugs using a heater array
With the aim toward realizing polymerase chain reaction (PCR) of deoxyribonucleic acid (DNA) in plug-based capillary platforms, this paper reports the theoretical and experimental results of thermocapillary actuation for ...
Thermocapillary actuation of droplet in a planar microchannel
A study on thermocapillary actuation of liquid droplet in a planar microchannel has been carried out by both theoretical modeling and experimental characterization. The driving temperature gradients are provided by four ...
Kinematics and deformation of ferrofluid droplets under magnetic actuation
This paper reports the experimental results on kinematics and deformation of ferrofluid droplets driven by planar coils. Ferrofluid droplets act as liquid magnets, which can be controlled and manipulated by an external ...
