Final dissemination event organized by SCARABEUS

1 August, 2023/in News /by jose

As the SCARABEUS project is reaching to an end, it is time to organise the final dissemination event in the form of an international conference. To this end, SCARABEUS has agreed to co-locate this event with the 7^th International Seminar on Organic Rankine Cycle (ORC) Power Systems, held in Seville between September 4^th and 6^th.

The International Seminar on ORC Power Systems is organised biennially by the Knowledge Centre on Organic Rankine Cycle Technology – KCORC, the reference organisation for the dissemination of all information related to ORC technology research, development and education. KORC promotes the interdisciplinary knowledge exchange between dedicated international professionals from academia, industry, governmental agencies and policy makers, with the aim is to advance the research, development and implementation of ORC technology by means of providing relevant technical and scientific information, organizing technical conferences and workshops, fostering engineering education, and advising on proper regulation. The seventh edition of the conference is hosted by University of Seville, an SCARABEUS partner.

The SCARABEUS dissemination event will be held on Wednesday, September 7^th, parallel to and jointly with the sessions of ORC 2023. This will facilitate exposure to a large number of stakeholders from different backgrounds, hence ensuring maximum outreach of the results. The event is comprised of technical presentations disclosing the main results obtained throughout the project in all the relevant scientific and technical areas as well as high-level presentations of related projects funded by the European Commission which can take exploit synergies with SCARABEUS.

The event is sponsored by the European Commission and, hence, the registration fee is kept to a minimum, also giving access to the technical and keynote sessions of ORC 2023. More information about the event and how to register can be found on the conference website: Link

Paper on aerodynamic and mechanical design of large gas turbines presented by City, University of London and Baker-Hughes at ASME Turbo Expo, Boston (USA)

15 July, 2023/in Conference and journal papers /by jose

The results of the collaboration between City, University of London (United Kingdom) and Baker-Hughes (Italy) have been have presented at ASME Turbo Expo in Boston (USA). This joint research has taken place within Work Package 3 – Turbomachinery Design of SCARABEUS, aimed at developing turbine designs able to attain high efficiency when working with Carbon Dioxide mixtures at very high pressures and temperatures.

Turbine design is strongly influenced by the composition of the working fluid because of the impact of this feature on the operating conditions of the cycle that attain peak thermal efficiency, and also the impact of composition on fluid characteristics.

Flow field of three different designs of the exhaust section

The paper presents the results of the unsteady simulations of the last turbine stage and exhaust section to assess unsteady loads on the rotor, as well as aerodynamic losses in the diffuser and exhaust section. Rotordynamics are also studied.

The paper can be downloaded free of charge from the conference website (link). Check the abstract below:

In this paper, the design of a large-scale axial turbine operating with supercritical carbon dioxide (sCO₂) blended with sulfur dioxide (SO₂) is presented considering aerodynamic and mechanical design aspects as well as the integration of the whole turbine assembly. The turbine is 130 MW, designed for a 100 MWe concentrated-solar power plant with turbine inlet conditions of 239.1 bar and 700 °C, total-to-static pressure ratio of 2.94 and mass-flow rate of 822 kg/s. The aerodynamic flow path, obtained in a previous study, is first summarised before the aerodynamic performance is evaluated using both steady-state and unsteady 3D numerical models to simulate the aerodynamic performance of the turbine. Whole-annulus unsteady simulations are performed for the last turbine stage and the exhaust section to assess the unsteady loads on the rotor due to downstream pressure field distortion and to assess aerodynamic losses of the diffuser and exhaust section. The potential low engine order excitation on the last rotor stage natural frequency modes due to downstream pressure distortion is assessed. The design of the turbine assembly is constrained by current manufacturing capabilities and the proposed working fluid properties. High-level flow-path design parameters, such as pitch diameter and number of stages, are established considering a trade-off between weight and footprint, turbine efficiency and rotordynamics. Rotordynamic stability is assessed considering the high fluid density related to cross coupling effects. Finally, shaft end sizing, cooling system design and the integration of dry gas seals are discussed.
