RISZonal Hybrid RANS-LES Simulation of a 1.5-Stage Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This article introduces a novel method to conduct zonal hybrid RANS-large eddy simulations (LES) of turbomachinery configurations and demonstrates its application to a 1.5-stage turbine. The method extends the ...
A Numerical Test Rig for Turbomachinery Flows Based on Large Eddy Simulations With a High-Order Discontinuous Galerkin Scheme—Part III: Secondary Flow Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this final paper of a three-part series, we apply the numerical test rig based on a high-order discontinuous Galerkin scheme to the MTU T161 low-pressure turbine with diverging end walls at off-design Reynolds number ...
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 ...
