Local dynamic similarity concept as applied to evaluation of discharge co- efficients of cross-ventilated buildings. Part 2: Applicability of local dy- namic similarity concept

In order to perform detailed evaluation on the applicability of local dynamic similarity concept, which is described in Part 1, wind tunnel experiment was conducted under some conditions where the opening positions and the arrangement of buildings were changed in more complicated manner. As a result, it has been found that the discharge coefficient Cd can be predicted accurately from PR* for the most of opening positions, even if the approaching flow angle is varied or another building is standing near the opening. It has been also found that there are no substantial problems for predicting Cd from PR* when the direction of interfering crossflow is changed or there is wall/floor near the opening as disturbing the diffusion of incoming airflow. However, it should be known that the prediction accuracy of Cd is lowered when these conditions simultaneously occur.
