Abstract
Contra-rotating members are used for straightening a fluid flow. The members may take the form of propellers, fans or impellers. The contra-rotation eliminates tangential flow components, and most importantly, eliminates cylindrical vortices. The present invention finds specific use in applications in which toroidal vortices are employed and/or generated.
