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

  • Original language description

    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.

    Modelování vývoje mikro-struktury řízené reakčně-transportními procesy

  • Czech description

    Metoda diskrétních elementů je využita pro modelování morfogeneze částic. Nosič katalyzátoru nebo rostoucí částice polymeru jsou diskretizovány na mikro-elementy s binárními a ternárními silovými interakcemi. Silové interakce jsou visko-elastické. Pohybmikro-elementů je popsán Newtonovými zákony a růst mikro-elementů je popsán kinetikou prvního řádu. Toto modelování umožňuje popsat zaplňování pórů katalyzátoru, fragmentaci nosiče katalyzátoru a morfogenezi částice polymeru.
