Abstract: Turbomachinery fan optimization is a complex multidisciplinary process, which forces engineers to rely on strong theoretical assumptions and/or can be very computationally expensive. Additionally, with new constraints ...

Abstract: The present work is a contribution to understanding the windmilling operation of lowspeed fans. Such an operating situation is described in the literature, but the context (mainly windmilling of aeroengines) often involves ...

Abstract: The present work analyzes the three-dimensional unsteady flow structure of a low-speed low-pressure ratio axial fan stage operating at stall conditions. Unsteady numerical simulations were conducted with the elsA software, ...

Abstract: This paper aims for the analysis of experimental and numerical results of windmilling flow topologies far from freewheeling condition. Two major cooling fans were investigated: a baseline design and an innovative one meant ...

Abstract: This paper aims at underlining the existence of some generic properties of windmilling flows, partially spread in the literature but never clearly stated. Two kinds of axial machines are investigated from compressor mode ...

Abstract: To enhance turbine efficiency, it is essential to mitigate the loss generated by irreversible phenomena taking place in turbine flows, including boundary layers, shock waves, vortices, and trailing edge wakes. A fast and ...

Abstract: This study is carried out in the context of hot streak flows in high-pressure turbines, for which a correct prediction of the temperature evolution is required. The present work particularly focuses on the turbulence ...
