title = "Spatial attenuation of vorticity measurements by multi-wire probes",
abstract = "The attenuation introduced in measured vorticity quantities by the finite separation distances between the cluster of wires in nine and twelve wire vorticity probes is examined by using a three point model of the probe. The analysis demonstrates that the probes introduce a significant amount of spatial attenuation if the separation distances in the probe are significantly larger than three times the Kolmogorov length scale. In addition, the one dimensional spectra of the vorticity measured by the probe in isotropic turbulence do not satisfy the one-dimensional isotropic vorticity spectral relations for the high wave numbers due to the spatial attenuation. It is demonstrated that the effect of spatial attenuation on vorticity measurements is dependent on the shape of the three dimensional velocity spectrum which is being measured.",
