Some canonical examples of streamwise vortex structure for rotating components
conference contributionposted on 28.02.2014, 13:50 by J. Paul Gostelow, Stephen J. Garrett, Aldo Rona, David S. Adebayo
Nose cones, turbine blades and bearings have rotating components and represent very practical geometries for which the modal behavior of vortex structures is not completely understood. These three rather different physical cases are being studied. A common theme of competition between modes and vortex types, whether counter-rotating or co-rotating, emerges. The objective of ongoing work is to obtain physical confirmation, enhanced understanding and predictive capability for the vortex structures encountered in rotating machines.
