Data assimilation for aerothermal mean flow reconstruction using aero-optical observations: accounting for RANS model-form uncertainty

Autor: Ben Ali, Mohamed Yacine, Léon, Olivier, Donjat, David, Bézard, Hervé, Laroche, Emmanuel, Mons, Vincent, Champagnat, Frédéric

In this study, we investigate a Data Assimilation approach for the numerical reconstruction of turbulent aero-thermal flows, and more particularly of their average density fields. The proposed approach relies on an ensemble Bayesian inference method

IGLOO3D Computations of the Ice Accretion on Swept-Wings of the SUNSET2 Database

Autor: Radenac, Emmanuel, Gaible, Hélène, Bézard, Hervé, Reulet, Philippe

Publikováno v: SAE International Conference on Icing of Aircraft, Engines and Structures
SAE International Conference on Icing of Aircraft, Engines and Structures, Jun 2019, Minneapolis, United States. ⟨10.4271/2019-01-1935⟩

International audience; In the framework of the SUNSET2 program, ice accretion numerical tools were assessed against experimental data. The database of ice shapes was generated on CRM-like swept-wings in NASA's IRT wind tunnel. This paper discusses c

Assessment of scale adaptive simulation of a rotor of high pressure compressor

Autor: Marty, Julien, Gaible, Hélène, Bézard, Hervé

Publikováno v: ASME Turbo Expo
ASME Turbo Expo, Jun 2018, OSLO, Norway. ⟨10.1115/GT2018-76537⟩

International audience; The main design objectives of a high pressure compressor are the aerodynamic efficiency and the operating range (e.g. the surge margin). Those quantities are impacted by secondary and leakage flows occurring in the blade passa
