As simulation software COMSOL is used. The main philosophy was to combine theory and praxis in a way that motivates the students. In addition "soft skills" should be improved. This was achieved by project work as final examination. As underlying didactical principle the ideas of Bloom's revised taxonomy were followed. The paper basically focusses on educational aspects, e.g. how to structure the course, plan the exercises, organize the project work and include practical COMSOL examples.}, language = {en} } @inproceedings{MahdiDerschSchmitzetal.2022, author = {Mahdi, Zahra and Dersch, J{\"u}rgen and Schmitz, Pascal and Dieckmann, Simon and Caminos, Ricardo Alexander Chico and Teixeira Boura, Cristiano Jos{\´e} and Herrmann, Ulf and Schwager, Christian and Schmitz, Mark and Gielen, Hans and Gedle, Yibekal and B{\"u}scher, Rauno}, title = {Technical assessment of Brayton cycle heat pumps for the integration in hybrid PV-CSP power plants}, series = {SOLARPACES 2020}, booktitle = {SOLARPACES 2020}, number = {2445 / 1}, publisher = {AIP conference proceedings / American Institute of Physics}, address = {Melville, NY}, isbn = {978-0-7354-4195-8}, issn = {1551-7616 (online)}, doi = {10.1063/5.0086269}, pages = {11 Seiten}, year = {2022}, abstract = {The hybridization of Concentrated Solar Power (CSP) and Photovoltaics (PV) systems is a promising approach to reduce costs of solar power plants, while increasing dispatchability and flexibility of power generation. High temperature heat pumps (HT HP) can be utilized to boost the salt temperature in the thermal energy storage (TES) of a Parabolic Trough Collector (PTC) system from 385 °C up to 565 °C. A PV field can supply the power for the HT HP, thus effectively storing the PV power as thermal energy. Besides cost-efficiently storing energy from the PV field, the power block efficiency of the overall system is improved due to the higher steam parameters. This paper presents a technical assessment of Brayton cycle heat pumps to be integrated in hybrid PV-CSP power plants. As a first step, a theoretical analysis was carried out to find the most suitable working fluid. The analysis included the fluids Air, Argon (Ar), Nitrogen (N2) and Carbon dioxide (CO2). N2 has been chosen as the optimal working fluid for the system. After the selection of the ideal working medium, different concepts for the arrangement of a HT HP in a PV-CSP hybrid power plant were developed and simulated in EBSILON®Professional. The concepts were evaluated technically by comparing the number of components required, pressure losses and coefficient of performance (COP).}, language = {en} } @article{ChudobaButenwegPeiffer2004, author = {Chudoba, Rostislav and Butenweg, Christoph and Peiffer, F.}, title = {Technical information system for collaborative material research}, series = {Advances in engineering software}, volume = {Volume 35}, journal = {Advances in engineering software}, number = {Issue 10-11}, issn = {1873-5339 (E-Journal); 0965-9978 (Print)}, doi = {10.1016/j.advengsoft.2004.03.021}, pages = {747 -- 756}, year = {2004}, language = {en} } @inproceedings{ChudobaButenwegKuhlmann2002, author = {Chudoba, Rostislav and Butenweg, Christoph and Kuhlmann, Wolfram}, title = {Technical information system for collaborative material research}, series = {Sixth International Conference on Computational Structures Technology : [Prague, Czech Republic, 4 - 6 September 2002]}, booktitle = {Sixth International Conference on Computational Structures Technology : [Prague, Czech Republic, 4 - 6 September 2002]}, organization = {International Conference on Computational Structures Technology <6, 2002, Prag>}, pages = {1 -- 11}, year = {2002}, language = {en} } @article{HelsperFissan1982, author = {Helsper, Christoph and Fißan, H.
