Measured and ca!culated properties relevant to the flow in ventilared rooms are reported. The measuremen/s were obtained by Iaser-Doppler anemometly in a small-scale model room with a single square in/et. The ca!culations made use of a numericalprocedure which so/ves, in finite-difference form, the elliptic partial differential equations for three components o f velocity, the pressure, the turbulence energy and its dissipation rate. Calculated results are shown to be in e/ose agreement with the present measuremen/s and with other available experimental data. With this justijication, the procedure is used to quantify the dependence of the vetocity characteristics of different geometric arrangements. The results provide guide lines forthedesign of ventilation systems.
