The model assumes a constant volume for the granulation zone, but a variable overall volume for the fluidized bed to account for classified product removal. The model is used to study the effect of various process parameters on dynamics and process stability. Stability is shown to depend on the separation diameter of product removal and the flow rate of the injected liquid. A lower and upper range of separation diameters with stable process behavior are found. In an intermediate range instability in the form of self-sustained oscillations is observed. The lower stability boundary is in qualitative agreement with recent experimental observations (Schmidt, Bück, & Tsotsas, 2015); the upper boundary was reported in a theoretical paper by Vreman, Van Lare, and Hounslow (2009) based on a single zone model.}, keywords = {Layering granulation, Zone formation, Internal product classification, Population balance modeling, Stability analysis}, tags = {A3}, web_url = {//www.sciencedirect.com/science/article/pii/S1674200116300967}, ISSN = {1674-2001}, DOI = {http://dx.doi.org/10.1016/j.partic.2016.07.001}, author = {Neugebauer, C. and Palis, S. and Bück, A. and Tsotsas, E. and Heinrich, S. and Kienle, A.} } @Article { Kovacevic2016, title = {Shape Identification of Primary Particles in Potash Alum Aggregates Using Three-Dimensional Tomography Data}, journal = {Cryst.

Dynamic models of the main process equipment are used in order to capture dynamic behavior of hydrodynamics inside an actual system, which delivers the experimental validation data. The process itself is carried out in a pair of strongly coupled fluidized bed reactors. Furthermore, a cyclone is used for gas-solid separation and two loop seal siphons prevent gas leakages from one reactor to another. The experimental plant operated at Hamburg University of Technology, which is modeled here, comprises a circulating fluidized bed air reactor and a two-stage bubbling bed fuel reactor. Operation of the plant is carried out at ambient condition and so are the simulations. All the mentioned process units are connected into a flowsheet via material streams and the whole process is simulated for 750 s of runtime. Within this time, the fluidization velocity of the fuel and the air reactor are changed to mimic effects, which occur during actual operation. The simulation was closely accompanied by experiments at the experimental facility and the results of simulation and experiments were compared. The bed mass, solid circulation and pressure profiles were simulated with good agreement to experimental findings. Dynamic effects were captured by the simulations and the system’s response to varying the fluidization speed, that is the change of bed masses, was predicted correctly. Time scales, in which these changes occur, were in the same range for experiments and simulations.}, tags = {A2}, web_url = {http://www.sciencedirect.com/science/article/pii/S0032591016308890}, publisher = {Elsevier}, ISSN = {00325910}, DOI = {10.1016/j.powtec.2016.12.022}, author = {Haus, Johannes and Hartge, Ernst-Ulrich and Heinrich, Stefan and Werther, Joachim} } @Article { Haus2016a, title = {Analysis of a Two-Stage Fuel Reactor System for the Chemical-Looping Combustion of Lignite and Bituminous Coal}, journal = {Energy Technology}, year = {2016}, volume = {4}, number = {10}, pages = {1263--1273}, keywords = {chemical looping;coal;copper oxide;solid fuel;two-stage reactor}, tags = {A2}, web_url = {http://dx.doi.org/10.1002/ente.201600102}, publisher = {Wiley Online Library}, ISSN = {2194-4296}, DOI = {10.1002/ente.201600102}, author = {Haus, Johannes and Lyu, Kai and Hartge, Ernst-Ulrich and Heinrich, Stefan and Werther, Joachim} } @Article { Sander2016a, title = {Dynamisches Schichtwachstum und Schichtstabilität bei der Abscheidung von partikulärem Material aus Fluidströmen}, journal = {Chemie Ingenieur Technik}, year = {2016}, volume = {88}, number = {9}, pages = {1353-1354}, tags = {A1, B2}, author = {Sander, S. and Londershausen, T. and Schmidt, E. and Fritsching, U.} } @Article { Barrenechea2016, title = {Analysis of algebraic flux correction schemes}, journal = {SIAM J.

It focuses on the particle size distribution (PSD) which is an important quality parameter in solids process industry. It is influenced by different factors, e.g. apparatus design (weir and nozzle assembly) and process conditions (mass flow rate), respectively. In this study the apparatus design by an over and under flow weir configuration, used separately or in combination, is investigated to obtain the product properties at the outlet of the apparatus. Simulation results show how characteristic product data depend on the process conditions and apparatus design.

Auf der Basis vorhandener Modelle für den statischen Betrieb soll das dynamische Verhalten anhand der zeitabhängigen Trennfunktion analysiert werden. Hierfür werden im Rahmen zweier DFG-Teilprojekte des SPP 1679 „Dynamische Simulation vernetzter Feststoffprozesse“ zwei sich ergänzende Ansätze verfolgt. An der Technischen Hochschule Nürnberg wird die Partikelbewegung auf dem Siebboden untersucht. Hierzu wird den Einzelpartikeln mithilfe einer Hochgeschwindigkeitskamera eine Bahnkurve zugeordnet und der Einfluss der Eingangsparameter auf die Trennfunktion analysiert. Für die Parameterstudie wird ein Kreisschwingsieb eingesetzt. Der dynamische Einfluss bei sprungartiger und linearer Änderung des Massenstroms und der Dispersitätseigenschaften im Aufgabegut wird analysiert. In Kombination wird ein kinetisches oder wahrscheinlichkeitstheoretisches Modell für den dynamischen Betrieb ermittelt. An der Ruhr-Universität Bochum wird parallel die Modellierung der Siebklassierung mittels DEM durchgeführt. Wichtig ist die Parametervalidierungmittels realer Partikelbewegung und Trennfunktionen.
