조선소내 환기용 팬의 환기 성능 향상을 위한 시뮬레이션 기반의 날개 형상 개발

In The main purpose of the present work is the Development of Blade Shape for High Performance of Ventilation Fan Used in Shipyard by using CFD analysis. The design parameters affecting the efficiency of ventilation fan were analyzed for the design of blade shape with High Performance. The angle and area of the blade including the vane were selected as the main design parameters. Considering the design parameters, the airflow rate through the outlet was numerically estimated by CFD analysis. From the results of analyses, it was concluded that the outflow rate increased as the vane area was wider and the vane angle was more tilted to negative direction. And the wider blade area was, the more flow rate was produced through the outlet. Of the analyzed cases, the most improved blade shape showed increases up to 39% than the existing shape.
