Thermoosmosis of a near-critical binary fluid mixture: a general formulation and universal flow direction
Youhei Fujitani, Shunsuke Yabunaka
We consider a binary fluid mixture, which lies in the one-phase region near the demixing critical point, and study its transport through a capillary tube linking two large reservoi…
Universal direction in thermoosmosis of a near-critical binary fluid mixture
Shunsuke Yabunaka, Youhei Fujitani
We consider thermoosmosis of a near-critical binary fluid mixture, lying in the one-phase region, through a capillary tube in the presence of preferential adsorption of one compone…
Diffusiophoresis in a Near-critical Binary Fluid Mixture
Youhei Fujitani
We suppose that a rigid spherical particle is put into a binary fluid mixture with the critical composition in the homogeneous phase near the demixing critical point. A short-range…
Isothermal transport of a near-critical binary fluid mixture through a capillary tube with the preferential adsorption
Shunsuke Yabunaka, Youhei Fujitani
We study isothermal transport of a nonelectrolyte binary fluid mixture, which lies in the homogeneous phase near the demixing critical point, through a capillary tube connecting tw…
Drag Coefficient of a Rigid Spherical Particle in a Near-Critical Binary Fluid Mixture beyond the Regime of the Gaussian Model
Shunsuke Yabunaka, Youhei Fujitani
The drag coefficient of a rigid spherical particle deviates from the Stokes law when it is put into a near-critical fluid mixture in the homogeneous phase with the critical composi…
Drag Coefficient of a Circular Inclusion in a Near-Critical Binary Fluid Membrane
Hisasi Tani, Youhei Fujitani
We calculate the drag coefficient of a circular liquid domain, which is put in a flat fluid membrane composed of a binary fluid mixture lying in the homogeneous phase near the demi…
Drag coefficient of a liquid domain in a fluid membrane with the membrane viscosities being different across the domain perimeter
Hisasi Tani, Youhei Fujitani
We calculate the drag coefficient of a liquid domain in a flat fluid membrane surrounded by three-dimensional fluids on both sides. In the membrane, the tangential stress should be…
Fluctuation Amplitude of a Trapped Rigid Sphere Immersed in a Near-Critical Binary Fluid Mixture within the Regime of the Gaussian Model
Youhei Fujitani
The position of a colloidal particle trapped in an external field thermally fluctuates at equilibrium. As is well known, the ambient fluid is not a simple heat bath and the particl…
Undulation Amplitude of a Fluid Membrane in a Near-Critical Binary Fluid Mixture Calculated beyond the Gaussian Model Supposing Weak Preferential Attraction
Youhei Fujitani
We calculate the mean square amplitude of the shape fluctuation -- an equal-time correlation -- of an almost planar fluid membrane immersed in a near-critical binary fluid mixture.…
Undulation Amplitude of a Fluid Membrane Surrounded by Near-Critical Binary Fluid Mixtures
Youhei Fujitani
We consider the thermal undulation, or shape fluctuation, of an almost planar fluid membrane surrounded by the same near-critical binary fluid mixtures on both sides. A weak prefer…
A Variational Principle for Dissipative Fluid Dynamics
Hiroki Fukagawa, Youhei Fujitani
In the variational principle leading to the Euler equation for a perfect fluid, we can use the method of undetermined multiplier for holonomic constraints representing mass conserv…
Clebsch Potentials in the Variational Principle for a Perfect Fluid
Hiroki Fukagawa, Youhei Fujitani
Equations for a perfect fluid can be obtained by means of the variational principle both in the Lagrangian description and in the Eulerian one. It is known that we need additional…
