Abstract

This paper investigates the wake characteristics of rotating and static objects, typical of US Navy ship emitters, using a four-hole Cobra Probe. The Cobra Probe has the ability to measure unsteady 3D velocity. An in-situ calibration was performed and compared to manufacturer specifications. Agreement between the in-situ and manufacturer calibrations led to a practical assessment in a 3D turbulent flow field. The assessment provided insight into the wake of rotating and static objects, and further explored limitations and advantages of the Cobra Probe for subsonic wake flows.
