소형 원심형 팬의 형상변수가 성능에 미치는 영향에 대한 실험적 연구
Experimental Study for the Effect of Dimensional Parameters on the Performance of Small Centrifugal Fans
초록
The performance of a centrifugal fan depends on the dimensional parameters of impeller, such as the inlet and exit diameter, area ratio, relative flow angles to the blade, and number of blades. These design parameters, however, are inter-related, so it is very difficult to identify the effect of each parameter to the fan performance. In this experimental study the effect of the design parameters on the performance of a small centrifugal impeller being used for vacuum cleaners are investigated. Total 30 shrouded impellers with 120mm diameter were tested and the results were non-dimensionalized to compare their performance.
