WebDec 2, 2014 · My uni is equipped with 4-hole cobra probes which is capable of receiving flow within a 45 degree cone of acceptance. As the base of a bluff body dominated with re-circulating flow, cobra probe has difficulty measuring back flows (out of acceptance angle). So my question is: Webemitters, 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.
