    Numerical solution of quasi-hydrodynamic equations on non-structured triangle mesh
    Computer Research and Modeling, 2009, v. 1, no. 2, pp. 181-188

    A new flow modeling method on unstructured grid was proposed. As a basis system this method used quasi-hydro-dynamic equations. The finite volume method vas used for solving these equations. The Delaunay triangulation was used for constructing mesh. This proposed method was tested in modeling of incompressible flow through a channel with complex profile. The acquired results showed that the proposed method could be used in flow modeling in unstructured grid.

    Topological microstructure analysis of the TIP4P-EW water model
    Computer Research and Modeling, 2014, v. 6, no. 3, pp. 415-426

    Molecular dynamics (MD) simulations of rigid water model TIP4P-EW at ambient conditions were carried out. Delaunay’s simplexes were considered as structural elements of liquid water. Topological criterion which allows to identify the water microstructure in snapshot of MD cell was used to allocate its dense part. Geometrical analysis of water Delaunay’s simplexes indicates their strong flatness in comparison with a regular tetrahedron that is fundamentally different from the results for dense part of simple liquids. The statistics of TIP4P-EW water clusters was investigated depending on their cardinality and connectivity. It is similar to the statistics for simple liquids and the structure of this dense part is also a fractal surface consisting of the free edges of the Delaunay’s simplexes.
