SCIACOVELLI, Luca; GLOERFELT, Xavier (Cambridge University Press (CUP), 2017)
The influence of dense-gas effects on compressible wall-bounded turbulence is investigated by means of direct numerical simulations of supersonic turbulent channel flows. Results are obtained for PP11, a heavy fluorocarbon ... -
Article dans une revue avec comité de lecture;GLOERFELT, Xavier (Springer Verlag (Germany), 2019)
Large eddy simulations are carried out for flows in a channel with streamwise-periodic constrictions, a well-documented benchmark case to study turbulent flow separation from a curved surface. Resolution criteria such as ...

Communication avec acte(ASME, 2015)The design of an efficient organic rankine cycle (ORC) expander needs to take properly into account strong real gas effects that may occur in given ranges of operating conditions, which can also be highly variable. In this ...

Communication avec acte;GLOERFELT, Xavier (American Institute of Aeronautics and Astronautics, 2015)
The present study aims at getting better insight of the complex flow dynamics in a channel constricted by periodic hills. This is a popular test case ofer used to assess LES and RANS/LES models, which appears as a compendium ...
-
Communication avec acte(American Institute of Aeronautics and Astronautics, 2015)Restrictions on the maximum allowable time step of explicit time integration methods for direct and large eddy simulations of compressible turbulent flows at high Reynolds numbers can be very severe, because of the extremely ...
-
Communication avec acte(American Institute of Aeronautics and Astronautics, 2018)This work presents developments towards a deterministic symbolic regression method to derive algebraic Reynolds-stress models for the Reynolds-Averaged Navier-Stokes (RANS) equations. The models are written as tensor ...

Article dans une revue avec comité de lecture(Elsevier, 2015)This work aims at assessing different Uncertainty Quantification (UQ) methodologies for the stochastic analysis and robust design of Organic Rankine Cycle (ORC) turbines under multiple uncertainties. Precisely, we investigate ...
