Assessment of organic Rankine cycle part-Load performance as gas turbine bottoming cycle with variable area nozzle turbine technology
Motamed, Mohammad Ali; Nord, Lars O. (Peer reviewed; Journal article, 2021)Power cycles on offshore oil and gas installations are expected to operate more at varied load conditions, especially when rapid growth in renewable energies puts them in a load-following operation. Part-load efficiency ... -
Development of a simulation tool for design and off-design performance assessment of offshore combined heat and power cycles
Motamed, Mohammad Ali; Nord, Lars O. (Chapter, 2022)Ambitious targets for reducing carbon dioxide (CO2) emissions are set by Norwegian authorities to address the concerns about global warming. Emission reductions in the offshore heat and power sector can play a role in ... -
Dynamic modelling and simulation of the Graz Cycle for a renewable energy system
Mitterrutzner, Benjamin; Nord, Lars Olof; Motamed, Mohammad Ali; Sanz, Wolfgang (Peer reviewed; Journal article, 2024)Critical atmospheric carbon dioxide levels and, in response, an increasing shift toward variable renewable energy sources causes the need of transient operation for thermal power plants coupled with carbon capture and ... -
Improving the off-design efficiency of organic Rankine bottoming cycle by variable area nozzle turbine technology
Motamed, Mohammad Ali; Nord, Lars O. (Chapter, 2021)Organic Rankine cycles (ORCs) are expected to operate more at varied working conditions, especially when rapid growth in renewable energies put power generation technologies in variable load operation. A power cycle works ... -
Part-load efficiency boost in offshore organic Rankine cycles with a cooling water flow rate control strategy
Motamed, Mohammad Ali; Nord, Lars O. (Peer reviewed; Journal article, 2022)Global concerns regarding greenhouse gas emissions and global warming have necessitated the speed up in using renewable energies and more efficient use of fossil fuels in the oil and gas industry. Harvesting gas turbine ... -
Part-load thermal efficiency enhancement in gas turbine combined cycles by exhaust gas recirculation
Motamed, Mohammad Ali; Genrup, Magnus; Nord, Lars O. (Peer reviewed; Journal article, 2024)Gas turbine power plants are popular for offshore power generation due to high power density and their reliability. However, growing usage of renewable energies put gas turbines in a load following backup operation. These ...
