Henry's law, surface tension, and surface adsorption in dilute binary mixtures
Akira Onuki
Equilibrium properties of dilute binary fluid mixtures are studied in two-phase states on the basis of a Helmholtz free energy including the gradient free energy. The solute partit…
Thermoacoustic effects in supercritical fluids near the critical point: Resonance, piston effect, and acoustic emission and reflection
Akira Onuki
We present a general theory of thermoacoustic phenomena in supercritical fluids near the critical point in a one-dimensional cell. We take into account the effects of the heat cond…
High-speed observation of the piston effect near the gas-liquid critical point
Yuichi Miura, Mitsuru Ohnishi, Shoichi Yoshihara +6
We measured high-speed sound propagation in a near-critical fluid using a ultra-sensitive interferometer to investigate adiabatic changes of fluids on acoustic timescales. A sound…
Sheared Solid Materials
Akira Onuki, Akira Furukawa, Akihiko Minam
We present a time-dependent Ginzburg-Landau model of nonlinear elasticity in solid materials. We assume that the elastic energy density is a periodic function of the shear and tetr…
Molecular Dynamics Simulation of Heat-Conducting Near-Critical Fluids
Toshiyuki Hamanaka, Ryoichi Yamamoto, Akira Onuki
Using molecular dynamics simulations, we study supercritical fluids near the gas-liquid critical point under heat flow in two dimensions. We calculate the steady-state temperature…
