RISNumerical Analysis of Flow in a Transonic Compressor With a Single Circumferential Casing Groove: Influence of Groove Location and Depth on Flow Instability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of circumferential single grooved casing treatment on the stability enhancement of NASA Rotor 37 has been examined with computational fluid dynamics analysis. Stall inception mechanism of Rotor 37 is presented ...
Unsteady Flow Structure of Rotating Instability in a 1.5-Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady flow structure of the rotating instability (RI) in a 1.5-stage axial compressor is investigated through experimental and numerical analyses. In the tested compressor, the total pressure rise of the rotor ...
