Abstract
U ovom diplomskom radu je razvijena Euler-Lagrangeova formulacija pronosa u heterogenim poroznim formacijama. Kao osnova korišten je nestacionarni model tečenja koji je prethodno razvijen na osnovu stacionarnog modela FI. Cilj je bio napraviti model koji bi uz tečenje omogućio rješavanje i pronosa. Iz tečenja je iskorišten algoritam nestacionarnog proračuna (uz blage preinake) za rješavanje disperzivnog Eulerovog koraka, dok se advektivni Lagrangeov korak riješio pomoću metode povratnog praćenja čestica "particle backtracking". Model se verificirao na realnim primjerima i traser testovima te pokazao dobre rezultate, posebice u srednjim i malim heterogenim poroznim formacijama te advektivno dominantnim slučajevima pronosa.

Parallel abstract (English)
In this Thesis, Euler-Lagrange finite element solute transport model is developed. Basis for this model was the previously developed models: finite element algorithm of unsteady flow FI and random walk Lagrangian transport model. Developed model uses two steps: Lagrangian advective step with backtracking particle algorithm and Euler dispersive step with finite element unsteady algorithm. Developed model is verified on two real examples and tracer tests. Model shows good performances, especially in the cases of low and moderate heterogeneity and advection dominated transport.
