RISEvolution of Turbulence and Its Modification by Axial Casing Grooves in a Multi-Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This experimental study examines the evolution of turbulence across an axial compressor and its modification by semicircular axial casing grooves (ACGs) at the pre-stall and near the best efficiency (BEP) flowrates. The ...
Impact of Operating Conditions and Axial Casing Grooves on the Evolution of Flow Structure Across Blade Rows in an Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stereo particle image velocimetry (SPIV) measurements in a series of axial planes investigate the impact of operating conditions and semicircular axial casing grooves (ACGs) on the evolution of flow structure across multiple ...
Effect of the Axial Casing Groove Geometry on the Production and Distribution of Reynolds Stresses in the Tip Region of an Axial Compressor Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stereo-PIV data are used for investigating the effect of axial casing groove (ACG) geometry on the distribution, evolution, and production rates of turbulent kinetic energy (TKE) and Reynolds stresses near a rotor tip. The ...
Effect of Axial Casing Groove Geometry on Rotor-Groove Interactions in the Tip Region of a Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This experimental study characterizes the interactions of axial casing grooves (ACGs) with the flow in the tip region of an axial turbomachine. The tests involve grooves with the same inlet overlapping with the rotor blade ...
