Airflow characteristics of cross ventilation through different opening conditions

The aim of that study was to clarify the differences in airflow characteristics outside and at three points in a cross-ventilated room under six opening conditions: window-open; insect-screen; lace-curtain; fabric-curtain; combined condition with insect-screen and lace-curtain; and combined condition with insect-screen, lace-curtain and fabric-curtain. The air velocity was measured by four ultrasonic anemometers, during the summer of 2004. The results obtained are presented.
