Auralization of streamline vorticity in computational fluid dynamics data

Presents a new method for auralization of the vorticity of a streamline in a vector field. This technique involves using a composite tone formed by superimposing sine waves of various amplitudes whose frequency and amplitude vary in such a way as to give the perception that the resulting sound increases or decreases endlessly in pitch without ever extending beyond the listener´s range of audible frequencies. Continuous clockwise or counterclockwise rotations of a streamline resulting from vorticity can then be displayed aurally as an apparently continuous increase or decrease in pitch.
