RISLarge Eddy Simulation of Laminar and Turbulent Shock/Boundary Layer Interactions in a Transonic Passage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shock/boundary layer interactions (SBLI) are a fundamental fluid mechanics problem relevant in a wide range of applications including transonic rotors in turbomachinery. This paper uses wall-resolved large eddy simulation ...
Experimental and Computational Investigation of an Advanced Casing Treatment in a Single-Stage High-Speed Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An advanced casing treatment (CT) design was tested in a single-stage, high-speed axial compressor. The geometry of the casing included bent-axial slots applied near the rotor leading edge. Compressor performance and stall ...
Loss Prediction in an Axial Compressor Cascade at Off-Design Incidences With Free Stream Disturbances Using Large Eddy Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Axial compressors may be operated under off-design incidences due to variable operating conditions. Therefore, a successful design requires accurate performance and stability limits predictions under a wide operating range. ...
Loss Analysis of Unsteady Turbomachinery Flows Based on the Mechanical Work Potential
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Loss analysis is a valuable technique for improving the thermodynamic performance of turbomachines. Analyzing loss in terms of the “mechanical work potential” (Miller, R.J., ASME Turbo Expo 2013, GT2013-95488) provides an ...
Large Eddy Simulation of an Open Fan Blade at Full-Scale Reynolds Number
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large-scale commercial turbofan designs are typically evaluated early in the technology maturation phase through subscale rig tests, while evaluations at full scale can only feasibly occur much later in a given engine ...
