  • D’Ambros, Alessio; Kipouros, Timoleon; Zachos, Pavlos; Savill, Mark; Benini, Ernesto (MDPI, 2018-10-12)
    In this work, we investigate the computational design of a typical S-Duct that is found in the literature. We model the design problem as a shape optimization study. The design parameters describe the 3D geometrical changes ...
  • Anselmi, Eduardo; Zachos, Pavlos; Collins, Robert; Hassan, Mark (Unknown, 2016-10-11)
    This paper describes the design of a supercritical carbon dioxide [S-CO2] rig for bottoming power cycle applications. The final envisaged layout of the facility includes a fully coupled compressor-turbine system, a number ...
  • Li, Zhou (2016-04)
    A gas turbine engine is a complex and non-linear system. Its dynamic response changes at different operating points. The exogenous inputs: atmospheric conditions and Mach number, also add disturbances and uncertainty to ...
  • Migliorini, Matteo; Zachos, Pavlos; MacManus, David G (AIAA, 2019-09-16)
    The need to reduce aero-engine emissions and direct operating costsis driving the civil aerospace sectortowards considering more integrated propulsion systems. Many of the proposed novel aircraft architectures employ ...
  • Anselmi, Eduardo; Bunce, Ian; Pachidis, Vassilios; Zachos, Pavlos; Johnston, Michael (Southwest Research Institute, 2018-04-08)
    An experimental facility is currently under development at Cranfield University, aiming to explore supercritical carbon dioxide as a working fluid for future bottoming power cycle applications for Rolls- Royce. The initial ...
  • Brighenti, Giovanni; Anselmi, Eduardo; Zachos, Pavlos (2016-10-11)
    Parametric design studies for the preliminary assessment of physical footprint of Supercritical CO2 power plants are presented herein. The aim of the study is to quantify trade-offs between cycle efficiency and plant ...
  • Guerrero-Hurtado, Manuel; Zachos, Pavlos; MacManus, David G.; Migliorini, Matteo; Trapani, Giuseppe (AIAA, 2019-08-16)
    The unsteady flowfields generated by convoluted aero engine intakes are major sources of instabilities that can compromise the performance of the downstream turbomachinery components. This highlights theneed for high spatial ...
