摘要: Abstract The characterization of voids in liquids is important understanding the behavior many physical properties. In this work, we have used Voronoi polyhedra method, coupled with its complementary analysis Delaunay tessellation, to investigate changes local structure supercritical water varying densities. Calculations are done at three different densities 1.0, 0.7 and 0.35 g cm− 3 673 K also normal 298 K. addition, a further lower density 0.15 g cm− 3 considered same temperature. It found that volume available particles void radius increase decrease given distributions radii necks connecting two neighboring calculated their variation temperature discussed.
