Particle flows occur in a very wide range of industrial applications. In a Discrete element model (DEM) the motions of the individual particles in the system are tracked. The model simulates all the interactions between the particles and their environment. The goal is to predict the macro‐properties of the flow and the modelling of the separate particles is only as accurate as required for this global aim. It is necessary to simulate particles of many different sizes and densities interacting with complex shaped surfaces.
Dalelių judėjimo diskrečiųjų elementų modelis
Santrauka. Daugelyje industrinių taikymų nagrinėjamas dalelių judėjimas. Ši metodika remiasi visų dalelių sąveikos modeliavimu. Darbe keliamas tikslas ištirti ir prognozuoti tekėjimo makrosavybes, remiantis šiuo tikslu parenkamas modelio tikslumas. Kiekvieno eksperimento metu modeliuojamas labai didelio skaičiaus įvairių dydžių dalelių judėjimas, ištirta tokių dalelių sąveika su sudėtingos formos paviršiais. Aptartos lygiagrečiųjų algoritmų panaudojimo galimybės.
