RISA Data-Driven Method for the Derivation of Explicit Algebraic Reynolds Stress Models Applied to the Wake Losses of Low-Pressure Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces and validates a data-driven approach to improve the prediction of linear eddy viscosity models (LEVMs). The general approach is adopted in order to improve the wake mixing of low-pressure turbine (LPT) ...
Assessment of the DDES-γ Model for the Simulation of a Highly Loaded Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow over the linear low-pressure turbine cascade MTU-T161 at Re = 90,000 is analyzed using delayed detached eddy simulations (DDES). At this operating point, the low Reynolds number and the high loading of the blade ...
