Loss Breakdown in Axial Turbines: A New Method for Vortex Loss and Wake Detection From 3D RANS Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Analysis of the Unsteady Flow Field at Stall Conditions for a Low-Speed Low-Pressure Ratio Axial Fan With Full-Annulus Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
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, ...
Analysis and Modeling of Turbulence Anisotropy of a Swirled Hot Streak Flow
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
