RISOptimized Casing Treatment to Improve Stall Margin Under Circumferential Pressure Distortion in a High-Speed Axial Flow Fan
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An optimized axial slot casing treatment (OPCT) was designed that experimentally improves the stall margin by 7.31% with an efficiency gain of 1.94% at a design speed of 100% in a high-speed axial flow fan. Subsequently, ...
Experimental Investigation on the Effects of Inlet Circumferential Distortion and Optimized Casing Treatment in a Transonic Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Casing treatment has been widely adopted to enhance the operating range of compressors by extending the stall margin. In this article, a high-precision experimental investigation is conducted in a transonic ...
Generative Inverse Aerodynamic Design of a Single-Stage Turbine Using Conditional Denoising Diffusion Probabilistic Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The aerodynamic design of turbomachinery is crucial for the overall performance of aero engines and has long been a paramount field of research. Traditional design methods are categorized into forward and inverse ...
Unsteady Interaction Mechanisms of Axial-Slot Casing Treatment With Tip Region Flow in a Highly-Loaded Mixed-Flow Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influences of axial-slot casing treatment (ASCT) on the performance and unsteady tip region flow are experimentally and numerically investigated in a highly-loaded mixed-flow compressor. The total pressure ratio, stall ...
Integrated Design of Axial Slot Casing Treatment and Blades in a Low-Speed Single Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Casing treatment has been used to enhance the stability of axial-flow compressor by extending the stall margin; it also induces strong interaction with compressor blades, as demonstrated in the open literature. Revealing ...
