- Abstract
- A sirocco fan with forward-curved blades is mainly used when a high air volume is needed in a confined space. Generally, the efficiency of the sirocco fan is lower than that of the fan having the same size. To increase the efficiency of the sirocco fan, a guide vane was installed in the outlet part of the fan, thereby improving the passage of the airflow. The influence of the air flow by the guide vane was analyzed using computational fluid dynamics. The guide vane reduced the size of the recirculation zone, reduced the power up to 3.37%, and increased the static pressure efficiency. The static pressure efficiency reached the maximum as the chord length increased. The study also demonstrated the highest static pressure efficiency when the guide vane angle was 16~17 degree.
