Experimental Study of the Effects of Dimensional Parameters on the Performance of Small Centrifugal Fans
소형 원심형 홴의 형상변수가 성능에 미치는 영향에 대한 실험적 연구
Abstract
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 the number of blades. These design parameters, however, are inter-related, so it is very difficult to identify the effect of each parameter on the fan performance. In this experimental study the effects of the design parameters on the performance of a small centrifugal impeller being used for vacuum cleaners are investigated. A total of 30 shrouded impellers with 120mm diameter were tested and the results were non-dimensionalized to compare their performance.
