Mixing ventilation flow in an enclosure driven by a transitional wall jet
Confined Flows
Underlying Flow Regime 4-20
Abstract
Ventilation flows are of large importance with respect to human health, comfort and energy use in buildings and other enclosures. A correct understanding of the complex airflow associated with ventilation flows is a necessity to advance ventilation systems and to increase health and comfort and decrease energy use. Experiments and numerical simulations using computational fluid dynamics (CFD) are two important methods to obtain detailed information on these complex flow problems. This UFR presents reduced-scale particle image velocimetry measurements and steady RANS CFD simulations of mixing ventilation flow in a cubical generic enclosure driven by a low Reynolds number (transitional) wall jet. The results obtained with three RANS turbulence models are compared with the PIV measurement results in the vertical center plane parallel to the supply flow direction.
This UFR is of special relevance to UFR 4-11, and indirectly to AC 4-03.
