Mathematical modeling of heat and mass transfer of particles encapsulation in a fluidised bed Modelowanie matematyczne wymiany ciepła i masy w procesie pokrywania cząstek w złożu fluidalnym Abstract The mathematical model, which allows to predict changes of the coverage degree, the moisture content and temperature of particles in process time, was developed. Taking into account changes of the evaporation surface due to an increasing particles coverage degree in the encapsulation process allows to describe the evolution of particles parameters more adequately and to select of process rational parameters.Keywords: modelling, encapsulation, heat and mass transfer, the degree of coverage, fluidised bed Streszczenie Zaproponowano rozbudowany model matematyczny, który umożliwia wyznaczenie zmiany stopnia pokrycia, zawartości wilgoci i temperatury cząstek podczas ich pokrywania w złożu fluidalnym. Na podstawie zmian powierzchni parowania spowodowanych zwiększeniem stopnia pokrycia cząstek model ułatwia bardziej precyzyjny opis zmian ich parametrów oraz odpowiedni dobór parametrów procesowych.Słowa kluczowe: modelowanie, pokrywanie cząstek, wymiana ciepła i masy, stopień pokrycia, złoże fluidalne

“…The conditions and basic possible mechanisms of the transition of the granular bed in apparatuses of constant cross section into the state of fl uidization are discussed in detail in works [5,6]. For realization of the corresponding process an optimal height of the fl uidized material must be selected [7].…”

A mathematical model of the process of separation of granular materials by specifi c weight in fl uidized beds has been constructed on the basis of the conservation equations of mass and momentum of the heterogeneous media mechanics. Computational and physical experiments on studying the separation process have been carried out. The regime and design parameters of the apparatus that ensure the needed degree of granular material separation into fractions have been determined.
