RISA 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 ...
A Numerical Test Rig for Turbomachinery Flows Based on Large Eddy Simulations With a High-Order Discontinuous Galerkin Scheme—Part I: Sliding Interfaces and Unsteady Row Interactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this first paper of a three-part series, we present the extension and validation of the high-order discontinuous Galerkin scheme in DLR’s CFD-solver trace for scale-resolving simulations of unsteady row interactions. ...
The Unsteady Shock-Boundary Layer Interaction in a Compressor Cascade—Part III: Mechanisms of Shock Oscillation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The shock-boundary layer interaction in transonic flows is known to cause strong unsteady flow effects that negatively affect the performance and operability of blade and cascade designs. Despite decades of research on the ...
The Unsteady Shock–Boundary Layer Interaction in a Compressor Cascade—Part II: High-Fidelity Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the second part of this three-paper series, high-fidelity simulations of the transonic cascade TEAMAero at the aerodynamic design point with Rein=1.35×106 and Main=1.21 are presented. A high-order discontinuous Galerkin ...
A Numerical Test Rig for Turbomachinery Flows Based on Large Eddy Simulations With a High-Order Discontinuous Galerkin Scheme—Part II: Shock Capturing and Transonic Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the second paper of this three-part series, we focus on the simulation of transonic test cases for turbomachinery applications using a high-order discontinuous Galerkin spectral element method (DGSEM). High-fidelity ...
