| 요약2 | The purpose of this study is to provide information on static pressure loss and emission airflow characteristics according to the shape of ventilation cap. The static pressure loss by wind velocity of ventilation caps with a diameter of 100 mm was measured by experiment. At wind velocity of 2 m/s, the largest static pressure loss occurred in ventilation cap No. 7 as 251 Pa. In addition, a two-variable correlation analysis showed that variables that are highly correlated with static pressure loss are cap of adverse wind prevention, cap volume, cap open area. CFD was used to identify static pressure loss and airflow characteristics of ventilation caps by diameter. The largest static loss was 75 mm in diameter of cap No. 1 and 150 mm in diameter of cap No. 3. This showed that the open area of the ventilation cap compared to the cross section area of the duct affected the static pressure loss of the ventilation cap. |
