The Measurement of Spatial Vorticity Distributions Using Hot-Wire Anemometry Techniques.

摘要

A simple method for measuring spatial vorticity content employing hot-wire anemometry techniques is proposed for flows where the primary convective velocity is locally greater than the mean crossflow components. Errors associated with the technique are computed exactly and in simple linearized forms to illustrate its validity in a wide range of flows. Applications of the technique to the problems of an isolated trailing vortex and to a nominally unsteady flow field are discussed as examples. (Author)
