Modellbildung von Partikelwechselwirkungen bei dispersen Stoffsystemen - Grundlagen der Flockung

Dyląg M., Rosiński J., Kamieński J.

Czasopismo Techniczne. Mechanika

2008

R. 105, z. 5-M

79-88

At work conditions enabling the flockulation process, connected with the necessity to reduce of repelling forces value which appears between particles of the solid body were introduced and basic sizes and notions were defined. An attempt of working out the dynamic quantitative model based on population balance was carried out. In the model the opposed effects of agglomeration, cracking and erosion for forming flocks were taken into consideration.

Erstellung von modellgleichungen zur beschreibung von partikelwechselwirkungen bei flockungsprozessen. Teil 1, grundlagen der populationstheorie und des rechenmodells

Dyląg M., Rosiński J., Kamieński J.

Czasopismo Techniczne. Mechanika

2008

R. 105, z. 5-M

89-96

At work bases of the theory of balance were discussed of the population, the schedule serving for the description of the size of particles and it for changes occurring as a result of lawsuits of the urbanized area, cracking and erosion. In the particular theoretical bases of the method of balance of the population were discussed as well as equations of the quantitative, leaned among others model were derived for adopted assumptions and simplifications.

Calculation of thermophysical properties for solids with application of statistical thermodynamics

Avsec J., Marcic M.

Journal of Technical Physics

2001

Vol. 42, no 3

327-336

The paper deals with a mathematical model for calculation of the thermodynamic properties of solids. The mathematical model, based upon statistical thermodynamics, is designed to assess the impact of atom vibration, electron excitation and the effect of intermolecular energy between atoms in a crystal. To calculate the configuration integral, the perturbation theory was used with the Van der Waals model as perturbation. The temperature-variable coefficients were introduced into the model presented in this paper. Finally, the model was compared with the experimental data proving a good matching.
