Hi,
I'm trying to measure the steady state velocity field behind the wake of a bluff body in the wind tunnel. 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:
- Is there any probe/anemometer that measures the flow speed and flow direction (velocity) at a certain point in space. (capable of measuring back flow also)
- My first thought was the hot wire anemometer, but that only measures the flow speed and not the flow direction, is that right?
edited: Also I'd like to add, the probe need to be small.
Any suggestion will be greatly appreciated, thank you!
