Název v původním jazyce

Modeling of micro-structure evolution driven by reaction-transport processes

Popis výsledku v původním jazyce

The discrete element method is used for the modeling of the particle morphogenesis. Catalyst carrier or nascent polymer particle is discretized into micro-elements with binary and ternary interactions acting among individual micro-elements. Force interactions are considered to be visco-elastic, and are governed by the equations of Maxwell, Kelvin or a three parametric model. The movement of micro-elements is governed by the Newton's law and a first order reaction kinetics is considered for the growth ofmicro-elements. Discrete element modeling allows to describe the filling of the pore of the catalyst, the fragmentation of the catalyst carrier and the morphogenesis of polymer particle.
