Reciprocating thermocapillary plug motion in an externally heated capillary by Jiao, Zhenjun, Nguyen, Nam-Trung, Huang, Xiaoyang, Ang, Yi Zhen

“…The model considers the coupling effect between heat transfer in the capillary wall and the surface tension driven movement of the plug. Because surface tension depends on temperature, the transient temperature distribution determines the surface tension difference across a plug and thus its movement. …”

Thermocapillary effect of a liquid plug in transient temperature fields by Nguyen, Nam-Trung, Huang, Xiaoyang

“…The generated temperature field and temperature gradient drive a liquid droplet according to the temperature-dependent surface tension. In the initial stage, the transient temperature gradient spreads in the capillary wall much slower than the droplet itself, and thus leads to an interesting behavior of droplet motion as described in this paper. …”

Thermocapillary actuation of droplet in a planar microchannel by Jiao, Zhenjun, Huang, Xiaoyang, Nguyen, Nam-Trung, Abgrall, Patrick

“…In the modeling, the temperature distributions corresponding to transient actuation are calculated, and are coupled to the droplet through the surface tensions which drive the droplet to move inside the channel. …”
