A 0D approach fot extended operational modeling of air ejectors in thermal systems
Schillaci, Eugenio; Oliet Casasayas, Carles; Ablanque Mejía, Nicolás; Torras Ortiz, Santiago; Vemula, Jagadish Babu; Duponcheel, Matthieu; Bartosiewicz, Yann; Planquart, Philippe (Begell House, 2023)
Conference report
Restricted access - publisher's policyClassic ejector models work accurately only in normal operating conditions, i.e. when the primary flow is in supercritical conditions. Moreover, they do not take into account abnormal situations, such as when the primary ... -
Air ejector analysis in normal and abnormal modes, oriented to control purposes in aircraft systems
Schillaci, Eugenio; Oliet Casasayas, Carles; Vemula, Jagadish Babu; Duponcheel, Matthieu; Bartosiewicz, Yann; Planquart, Philippe (European Conference for AeroSpace Sciences (EUCASS), 2022)
Conference report
Restricted access - publisher's policyThe integration of Ultra High Bypass Ratio (UHBR) engines introduces important restrictions of space for the aircraft pylon, and as a consequence on the embedded bleed air system. Under this scenario, a reduction of the ... -
Air ejector znalysis in extended operational perimeter for control oriented simulation of bleed-air aircraft systems
Schillaci, Eugenio; Oliet Casasayas, Carles; Vemula, Jagadish Babu; Duponcheel, Matthieu; Bartosiewicz, Yann; Planquart, Philippe (Institute of Physics (IOP), 2023-06-28)
Article
Open AccessThe integration of large size Ultra High Bypass Ratio (UHBR) engines introduces new restrictions of space for their integration with the aircraft wing. Under this scenario, a reduction of the size of the bleed air system ... -
Calibration of the 0D model of an air ejector by means of compressible RANS simulations
Schillaci, Eugenio; Oliet Casasayas, Carles; Vemula, Jagadish Babu; Duponcheel, Matthieu; Bartosiewicz, Yann (Begell House, 2023)
Conference report
Restricted access - publisher's policyThis work analyzes the need to perform a series of CFD simulations in order to calibrate 0D ejector models. The proposed case study consists in the analysis of a supersonic air ejector used in the aeronautical field to ... -
Numerical modeling of air ejectors covering supersonic, subsonic and closed-port operations
Schillaci, Eugenio; Vera Gil, Jordi; Oliet Casasayas, Carles; Vemula, Jagadish Babu; Duponcheel, Matthieu; Bartosiewicz, Yann (Elsevier, 2024-09-01)
Article
Open AccessThe physics and modeling of air ejectors in on- and off-design conditions have been extensively addressed in the past, reaching a good level of maturity. However, to achieve a robust model at system scale integrating an ...
