Especially for seasonal storage, power-to-gas can be a promising approach. Biologically produced methane from hydrogen produced from surplus electricity can be used to substitute natural gas in the existing infrastructure. Current reactor types are not or are poorly optimized for flexible methanation. Therefore, this work proposes a new reactor type with a plug flow reactor (PFR) design. Simulations in COMSOL Multiphysics ® showed promising properties for operation in laminar flow. An experiment was conducted to support the simulation results and to determine the gas fraction of the novel reactor, which was measured to be 29\%. Based on these simulations and experimental results, the reactor was constructed as a 14 m long, 50 mm diameter tube with a meandering orientation. Data processing was established, and a step experiment was performed. In addition, a kLa of 1 h-1 was determined. The results revealed that the experimental outcomes of the type of flow and gas fractions are in line with the theoretical simulation. The new design shows promising properties for flexible methanation and will be tested.}, language = {en} } @article{KuertenMottaghyZiegler2015, author = {K{\"u}rten, Sylvia and Mottaghy, Darius and Ziegler, Martin}, title = {Design of plane energy geostructures based on laboratory tests and numerical modelling}, series = {Energy and Buildings}, volume = {107}, journal = {Energy and Buildings}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0378-7788}, doi = {10.1016/j.enbuild.2015.08.039}, pages = {434 -- 444}, year = {2015}, language = {en} } @article{RochefortVerverGrunendahletal.2005, author = {Rochefort, E. de and Verver, M. and Grunendahl, A. and Mooi, H. and Butenweg, Christoph}, title = {Detailed modelling of the lumbar spine for investigations of low back pain}, series = {SAE transactions : papers presented at Society and Section meetings / Society of Automotive Engineers}, volume = {Volume 114}, journal = {SAE transactions : papers presented at Society and Section meetings / Society of Automotive Engineers}, number = {Part 7}, organization = {Society of Automotive Engineers}, issn = {0096-736X}, pages = {788 -- 796}, year = {2005}, language = {en} } @article{KernSchelthoffMathieu2011, author = {Kern, Alexander and Schelthoff, Christof and Mathieu, Moritz}, title = {Detaillierte Berechnung der Einfangwirksamkeiten von Fangeinrichtungen mit einem dynamischen elektro-geometrischen Modell - Detailed calculation of the interception efficiencies for airtermination systems using a dynamic electro-geometrical model}, pages = {1 -- 5}, year = {2011}, language = {de} } @article{HelsperMoelter1987, author = {Helsper, Christoph and M{\"o}lter, W.}, title = {Determination and Neutralization of the Charge Produced by the Dispersion of Powders}, series = {Journal of Aerosol Science. 18 (1987), H. 6}, journal = {Journal of Aerosol Science. 18 (1987), H. 6}, isbn = {0021-8502}, pages = {877 -- 880}, year = {1987}, language = {de} } @article{HelsperFissanThielen1983, author = {Helsper, Christoph and Fißan, H.

The solid displacements and the pressures of both water and air phases are unknowns of the proposed model. The finite element method is used to solve the governing differential equations. The proposed method is demonstrated through simulation of seepage test and partially consolidation problem. Then, implementation of the model is done by using hypoplasticity for the solid phase and analyzing the fully saturated triaxial experiments. In integration of the constitutive law error controlling is improved and comparisons done accordingly.
