Pressure-drop localization and momentum insulation in liquid-gas coexistence Poiseuille flow
Naoko Nakagawa, Shin-ichi Sasa
We study pressure-driven Poiseuille flow of a one-component fluid between adiabatic plates in liquid-gas coexistence. The analysis uses Poiseuille flow and Fourier heat conduction…
Global thermodynamics for heat-conducting fluids under weak gravity
Naoko Nakagawa, Shin-ichi Sasa
We study liquid-gas coexistence under gravity and heat conduction from the viewpoint of global thermodynamics. We construct a variational free-energy function for the fixed-global-…
Thermodynamic Variational Principle Unifying Gravity and Heat Flow
Naoko Nakagawa, Shin-ichi Sasa
Predicting the stable phase configuration in a liquid-gas system becomes a fundamental challenge when the stratification favored by gravity conflicts with arrangements induced by h…
Gibbs Factorials Become Kinetic in History-Dependent Reactions
Nanako Hirano, Akira Yoshida, Takenobu Nakamura +1
Gibbs factorials are usually regarded as equilibrium counting factors. We show that they can also appear directly in a measurable kinetic observable when products formed at differe…
Global thermodynamics for isothermal fluids under gravity
Naoko Nakagawa, Shin-ichi Sasa, Takamichi Hirao +3
We develop a formulation of global thermodynamics for equilibrium systems under the influence of gravity. The free energy for simple fluids is extended to include a dependence on $…
Non-equilibrium phase coexistence in boundary-driven diffusive systems
Shin-ichi Sasa, Naoko Nakagawa
Liquid-gas phase coexistence in a boundary-driven diffusive system is studied by analyzing fluctuating hydrodynamics of a density field defined on a one-dimensional lattice with a…
