    A two-structure model of themrodynamic properties and surface tension of supercooled water

  • Original language description

    A thermodynamic model was developed describing the liquid and gaseous phases of water. The model correctly represents the strong anomalous behavior of supercooled water. The anomalies are due to the vicinity of liquid-liquid critical point. The model approximates liquid water as a mixture of two competing structures (high- and low-density structure) and cavities. The thermodynamic state is found by minimizing the Gibbs free energy with respect to the proportion of the two structures and number of cavities. The mixture approach is further used to model the surface tension.

    Dvou-strukturní model termodynamických vlastností a povrchového napětí podchlazené vody

  • Czech description

    Byl vyvinut termodynamický model popisující kapalnou a plynnou fázi vody. Model správně reprezentuje silné anomální chování podchlazené vody. Anomálie jsou způsobeny blízkostí kritického bodu kapalina-kapalina. Model aproximuje kapalnou vodu jako směs tvou soutěžících struktur (vysoko- a nízko-hustotní struktura) a kavit. Termodynamický stav je nalezen minimalizací Gibbsovy volné energie vzhledem k proporci obou struktur a počtu kavit. Tento přístup je dále použit pro modelování povrchového napětí.
