RISControl of Three-Dimensional Corner Separation Flow in a Highly Loaded Compressor Cascade via Dynamic Surface Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When the Reynolds (Re) number decreases below the critical value, the intensified turbulent mixing in the corner region rapidly deteriorates the performance of compressors, including efficiency and stability. However, ...
Effect of a Submerged Rectangular Barrier Structure in the Lake Entrance Area on the Flow Field
Publisher: American Society of Civil Engineers
Abstract: AbstractThe investigation of the flow field driven by the submerged structures in the lake
entrance area is helpful for preventing excessive delivery of sediment into the main
lake area. Taking the lake entrance area as ...
Investigation on the Flow and Loss Mechanism of Supersonic Through-Flow Variable-Pitch Tandem Cascade Under Extremely Wide-Speed Range Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The supersonic through-flow variable-pitch tandem cascade has a significant potential for widening the acceptable inflow range of fans, but its internal flow mechanisms are not yet fully understood. This study ...
Mechanism of Low-Frequency Oscillation in the Compressor Corner Region and Its Deterministic Impact on Loss Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The loss generation in the corner region of compressors is highly dependent on vortex dynamics. When the Reynolds number (Re) decreases to a critical value, the flow unsteadiness induced by multiscale vortex ...
