Optothermal Actuation of Unidirectional Thermo-osmotic Flows
Tetsuro Tsuji, Shota Suzuki, Satoshi Taguchi +2
In this paper, we experimentally demonstrate the microscale direction control of thermoosmotic flows using a focused-laser heating. The key is the off-center laser irradiation on a…
Slow uniform flow of a rarefied gas past an infinitely thin circular disk
Takuma Tomita, Satoshi Taguchi, Tetsuro Tsuji
The classical problem of steady rarefied gas flow past an infinitely thin circular disk is revisited, with particular emphasis on the gas behavior near the disk edge. The uniform f…
Optically-Trapped Particle Tracking Velocimetry
Tetsuro Tsuji, Shoma Hashimoto, Satoshi Taguchi
In this paper, we propose a microflow velocimetry based on particle tracking with the aid of optical trapping of tracers, namely, optically-trapped particle tracking velocimetry (o…
Slip-flow theory for thermo-osmosis based on a kinetic model with near-wall potential
Tetsuro Tsuji, Koichiro Takita, Satoshi Taguchi
In this paper, thermal-slip coefficients in slip boundary conditions of the Stokes equation are derived using the generalized slip-flow theory, with special interest in the role of…
Semi-analytical model of optothermal fluidics in a confinement
Tetsuro Tsuji, Shun Saito, Satoshi Taguchi
In this paper, we provide the semi-analytical solution of the temperature and flow fields of a fluid confined in a narrow space between two parallel plates. The temperature increas…
