Liquid-like behavior of supercritical fluids
, 2006 The high frequency dynamics of fluid oxygen have been investigated by Inelastic X-ray Scattering. In spite of the markedly supercritical conditions ($T\approx 2 T_c$, $P>10^2 P_c$), the sound velocity exceeds the hydrodynamic value of about 20%, a ...

Hydraulic flow through a channel contraction: multiple steady states [PDF]
, 2007 We have investigated shallow water flows through a channel with a contraction by experimental and theoretical means. The horizontal channel consists of a sluice gate and an upstream channel of constant width $b_0$ ending in a linear contraction of ...

Underground hydrosphere and geofluids of the Earth’s crust and upper mantle
Геофизический журнал, 2017 The physicochemical state of the water at various temperature and pressure conditions of the Earth’s interior has been characterized. Two groups of geofluidic systems for water have been established: subcritical (T < 374 ¸ 450 °Ñ) and supercritical (T >
