Report on the research internships in Norway before July 2022

Three researchers from Negative CO2 Emission Gas Power Plant (nCO2PP) project took part in research internship at Norwegian University of Science and Technology (NTNU) at the Department of Energy and Process Engineering (EPT) and SINTEF Energy Research Institute in Trondheim, Norway, as part of the Polish-Norwegian cooperation.

Prof. Paweł Madejski research stay at NTNU concerned the definition of common assumptions for the development of the geometry of the Spray Ejector Condenser (SEC), planned to be made and tested experimentally on the WP5 test stand, as well as the determination of the scope and assumptions for the implementation of numerical studies and experimental tests on SEC operating parameters. During the visit, meetings and discussions took place between the leaders of tasks 1-3 in WP5: prof. Krzysztof Banasiak (SINTEF) and prof. Paweł Madejski - (AGH). The most important conclusions and results made it possible to develop SEC operating parameters for two variants of LPL and HPL analyzed in the next stage of the project. The result was also the development of limitations and recommendations for the selection of test stand components, taking into account the possibility of implementing and assessing the process of water vapor condensation in the presence of CO2, measuring the basic operating parameters of SEC, and taking into account the possibility of gaseous and liquid CO2 (CO2 dissolved in water). During the visit, prof. Paweł Madejski, also had the opportunity to tighten cooperation with dr Chao Fu (WP2 Leader) and prof. Ivar Stale Ertesvag (Task 3, WP2 leader) in order to develop numerical models of the cycles developed in the project, and to conduct thermodynamic analyzes in the Ebsilon program.

Recruitment for the implementation of master's theses is underway. We encourage all students in the fields of Mechanics and Machine Design, Power Engineering or International Design Engineer who are interested in the subject of broadly understood energy, thermodynamic cycles, combustion, gas turbines, steam turbines and heat exchangers to contact. As part of the project, it is possible to carry out a master's thesis on a current subject and get acquainted with the problems and new concepts that today's science is struggling with.

Contact person: dr inż. Paweł Dąbrowski –
