Don’t Miss Out on These Presentations!

The following papers will be presented at the ASME Turbo Expo, and the technology used in these presentations is Cadence Fidelity LES.

GPU-Accelerated Full-Wheel Large-Eddy Simulations of a Transonic Fan Stage 

Session: 34-08 LES Solvers and Applications 2

Cadence CFD has harnessed advances in numerical algorithms and computer hardware to overcome the limitations of traditional high-fidelity methods such as large eddy simulation (LES). A detailed simulation of the NASA 67 single-stage transonic axial-flow fan is conducted by leveraging the Fidelity LES solver. This simulation covers the fan's operation at full speed, including the use of two mesh types with millions of control volumes and employing advanced turbulence models. The resulting performance curves agree with experimental data and represent a significant achievement in computational fluid dynamics applied to turbomachinery.
 
Coupled Design of Multi-Component Distortion-Generating Devices for Aircraft Engine Ground Tests
Part I: Design Methodology and Numerical Validation

Part II: Experimental Characterization in a Closed-Loop, High-Speed Test Rig

Session: 01-05 Inlet Distortion and Engine Operability I

Advanced aircraft engine configurations like Ultra High Bypass Ratio (UHBR) engines, Blended Wing Bodies (BWB), and Boundary Layer Ingestion (BLI) configurations experience significantly higher flow distortion at the fan inlet compared to current designs. This non-uniform inlet flow can drastically affect engine performance, operability, and vibration, necessitating extensive testing to assess engine-airframe incompatibilities.

The first presentation on this topic covers the development of a numerical design methodology capable of reproducing complex and realistic distortion patterns, the design of distortion devices, and the experimental validation of 3D-printed screens using computational fluid dynamics and machine learning. The second presentation focuses on testing the distortion screens in a high-speed test rig and compares the results with the design target patterns to assess the design method and identify potential improvements.

Large Eddy Simulation of Turbulent Reacting Flow in a Pressurized Annular Combustor

Session: 04-16 Combustion Modeling IV

Large-eddy simulations (LES) are increasingly used in engineering to predict complex physical interactions in propulsion systems with realistic combustors. This presentation aims to demonstrate LES's ability to capture turbulence, flame dynamics, and performance parameters in a realistic full-annular combustor from the Energy Efficient Engine (E3) program. The study uses the massively parallel LES solver to model turbulence-chemistry interactions and investigate the effects of grid resolution.

This work is supported by the DoD High-Performance Computing Modernization Program (HPCMP) Frontier program at ARL and NAVAIR in collaboration with the University of Cincinnati, Cascade Technologies, and Pratt & Whitney.
