3889 -- Field Measurements of Boundary-Layer Flows in Ventilated Rooms PDF

Describes the measurement under field conditions of air velocity and turbulent kinetic energy near the surfaces of walls, ceilings, floors and furnishings for four space layouts of an office building - a partitioned office room, a single office room, a small conference room and a computer room. The objectives were to determine the range of velocity and turbulence levels and their characteristics near the surfaces under realistic ventilation conditions and to provide field data for developing empirical models of the boundary layer flows. Presents and discusses the results. States they will be useful for establishing proper air flow conditions when conducting material emission tests using small or large chambers and developing methods to extrapolate the chamber test data to predict the volatile organic compounds emission rates in real environments.
