Particle mixing in bubbling fluidized beds of binary particle systems
Autor: Natalia Iwanowa, Manfred C. Wirsum, Genadij Lukjanow, Franz N. Fett
Publikováno v: Powder Technology. 120:63-69
The mixing and segregation behavior of spherical solids between 20 and 40 mm in diameter in a bubbling fluidized bed of quartz sand was investigated. The experimental system used is a cold-air fluidized bed of 0.45×0.45 m bed area and about 0.5 m be

Experimental study and modelling of char combustion under fluidized bed conditions
Autor: Franz N. Fett, Manfred C. Wirsum, Xiangdong Xu, Yongzhe Zhang, Stefan Hamel
Publikováno v: Journal of Thermal Science. 7:264-271
The combustion behavior of chars from two Chinese coals has been investigated in a laboratory scale bubbling fluidized bed system in Siegen University, Germany. Experimental equipment and method are introduced. The ‘shrinking-core’ model and the

Steigerung der Rechengenauigkeit bei der Wirbelschichtsimulation durch vom Rechner automatisch gebildete algebraische Ableitungen
Autor: Heiner Edelmann, Franz N. Fett
Publikováno v: Chemie Ingenieur Technik. 62:1037-1039
On presente une methode algebrique permettant d'ameliorer la precision des calculs lors de la simulation de lits fluidises. Cette methode est appliquee a la simulation de combustion en lit fluidise

THEORETICAL AND EXPERIMENTAL ANALYSIS OF DESIGN AND OPERATION OF MULTI-ENERGY SOURCE HEATING SYSTEMS
Autor: Wolfgang Krumm, Franz N. Fett, H. Bradke
Comparison of simulation results with experimental results for a multi-energy source heating system are presented. The heating system consists of a compact energy-absorber-heat pump system with an integrated cold water storage. A laboratory building
