| Abstract | : | In this paper, the characteristics of air change rate, flow and pressure fields in and aroud building models with wind-induced ventilation are studied using wind tunnel experiment. The results are as follows. 1. The airflow through an open window into the room model still preserves a large part of its mean kinetic energy when it remains inside the room. A major part of its preserved energy is directly convected outside the room model through a leeward window without interior dissipation. 2.Therefore the characteristics of cross ventilation are completely different from those of air infiltration. It is reflected as the decreases of values of ζ in the case of cross ventilation, compared to those values in the case of air infiltration. 3. Power balance model, which is deduced from the 3-D conservation law of kinetic energy, well explains these situation. 4. Lost powers and total pressure loss coefficients, ζ , at various openings are examined by applying the power balance model to the experimental cases. The predicted values of ζ show reasonable results and the usefulness of the power balance model is validated. |
