Both methods have been compared in terms of accuracy and computational effort. It is shown that they give comparable results if all numerical parameters are controlled carefully. LBM requires a much higher computational effort, however, in contrast to ASD it is able to simulate partially sintered agglomerates as well. The results show that even a very small amount of sintering leads to a significant reduction in the drag force. The analysis of the drag force on agglomerates as well as on aggregates shows that there is no simple geometric quantity which is uniquely related to the drag force. Moreover, there is a significant variation in drag force for single aggregates at different orientations or for the orientation averaged drag force of different aggregates of the same size. This is explained by the structural effects which may lead to a variation in the drag force up to +-20%.}}, author = {{Binder, Christian and Feichtinger, Christian and Schmid, Hans-Joachim and Thürey, Nils and Peukert, Wolfgang and Rüde, Ulrich}}, issn = {{0021-9797}}, journal = {{Journal of Colloid and Interface Science}}, number = {{1}}, pages = {{155--167}}, title = {{{Simulation of the hydrodynamic drag of aggregated particles}}}, doi = {{10.1016/j.jcis.2006.04.045}}, volume = {{301}}, year = {{2006}}, } @article{26148, abstract = {{Die Modellierung der wandnahen Bereiche bei der Simulation von Zweiphasenströmungen spielt in der Praxis eine entscheidende Rolle, wenn erwünschter oder unerwünschter Transport der dispersen Phase zu einer Oberfläche bedeutend ist.

Growth due to surface reaction and due to condensation is related to the fraction of the surface area that is exposed to the collision with single molecules. Surface shielding is found to hamper surface reaction and condensation once fractal aggregates start to form. It leads to significantly retarded precursor consumption and produces aggregate particles, which consist of more, but smaller primary particles. Surface energy data are varied within a range as proposed by available literature data. Moderate and high surface energy values result in a thermodynamic barrier to the formation of new particles and are shown to reduce the formation of seed particles by several orders of magnitude. This leads to the formation of aggregate particles which consist of a rather small number of primary particles and mainly grow by surface reaction. The primary contribution of condensation to growth of individual primary particles is shown to be very little. However, condensation should not be neglected as it has a strong impact on particle formation rates and hence on product characteristics such as the number of primary particles and primary particle size.}}, author = {{Artelt, C. and Schmid, Hans-Joachim and Peukert, W.}}, issn = {{0009-2509}}, journal = {{Chemical Engineering Science}}, number = {{1}}, pages = {{18--32}}, title = {{{Modelling titania formation at typical industrial process conditions: effect of surface shielding and surface energy on relevant growth mechanisms}}}, doi = {{10.1016/j.ces.2004.12.053}}, volume = {{61}}, year = {{2006}}, } @book{26721, author = {{Hellmich, Frank and Kiper, Hanna}}, publisher = {{Beltz}}, title = {{{Einführung in die Grundschuldidaktik }}}, year = {{2006}}, } @inbook{26795, author = {{Wernke, Stephan and Hellmich, Frank}}, booktitle = {{Beiträge zum Mathematikunterricht 2006}}, pages = {{255--258}}, publisher = {{Franzbecker}}, title = {{{Lernstrategien, Metakognitionen und Motivationen von Kindern im Mathematikunterricht. }}}, year = {{2006}}, } @article{26798, author = {{Hellmich, Frank}}, journal = {{Grundschule}}, pages = {{46--47}}, title = {{{Gewusst wie! – Lernstrategien von Kindern.
