Recent Insights into the Flow Topology Around Highly Loaded Tandem Vanes

Abstract: A large share in the weight of aero engines is attributed to the compressor module. Weight savings are crucial for the increase of overall propulsion system efficiencies. This has led to a steady reduction of stage counts in axial compressors, implying a constant increase in stage pressure ratios. The socalled tandem blade configuration represents an innovative approach. The blades within a row are being replaced by pairs of blades placed successively in the streamwise direction, leaving a slot between the fro… Show more

“…They proved a good performance for the tandem stator at varying flow conditions. Heinrich et al (2015), Tiedemann et al (2017), Heinrich et al (2017) as well as Heinrich and Peitsch (2019) investigated the flow topology of tandem blades at a cascade with respect to secondary flow structures. They showed that the gap flow has a strong influence on the boundary layer of the rear blade, resulting in different corner vortex formation.…”
