Turbulent Anisotropy and Dissipation/Production in the Indoor Environment

In the effort towards CFD validation and turbulent model calibration, various numerical terms are determined using various data sources such as DNS or experimental results. The presented research includes a series of PIV experiments and corresponding turbulent analysis in order to quantify these terms in the indoor environment. A variety of configurations are given to determine common values in such flow regimes as well as information critical to the CFD community for specific ventilation situations. Using a displacement ventilation design, where the heated body of the indoor occupant drives the flow, three components of velocity are presented around a breathing thermal manikin in various positions for a multi- faceted view of experimentally determined turbulence in the indoor environment. Specifically, an integrated length scale analysis in conjunction with the turbulent anisotropy and dissipation/production information is presented.
