Abstract: | This paper describes anisotropy of various second moments along with detailed mean velocities in the human breathing zone.
High anisotropy levels have been anticipated due to the complexity of the flow and low Reynolds number in our cubicle sized
setting. The measurement system is a standard stereo PIV system acquiring data along a sinusoidal breathing waveform in the
breathing zone of a thermal manikin both with and without rotational motion. Results suggest that the airflow due to breathing
is anisotropic. Because of this, common isotropic assumptions made in this environment are not admissible. |
