    Model numeryczny odwodnienia złoża węgla brunatnego Złoczew
    (Wydawnictwa AGH, 2011) Strzelecki, Tomasz; Strzelecki, Michał
    The paper presents the results of numerical calculations of draining the Złoczew lignite deposit with finite element method. The paper is a part of pre feasibility study report. The numerical model was made using FlexPDE v 6 soft. At calculation of the model a previously performed analysis of hydrogeological and geological conditions containing among others of supplying water, proposals of the way of draining and carrying underground waters.

    Obliczenia numeryczne tensora przepuszczalności Darcy'ego w oparciu o metodę asymptotycznej homogenizacji
    (2008) Strzelecki, Tomasz
    The paper deals with numerical determination of Darcy permeability tensor for periodic porous medium with VRE being the unit cell. The calculations are performed for 2D and 3D cases. The influence of porosity on the permaeability tensor is studied by considering a simplified geometry of porous medium. It is pointed out, for instance, that values of permeability tensor obtained are of the same order as for natural rocks as sandstone if the size of VRE is of the order of diameter of sandstone grains.
