Abstract
This paper describes the performance of a centrifugal fan used for refuse collection systems according to the chord length of the splitters installed near the blade suction and pressure surface sides. The fan performance is analyzed by three-dimensional Navier.Stokes analysis and is compared to the results obtained experimentally. Throughout the numerical simulation of the fan with splitters, it is found that the reverse-flow region observed near the suction side of the blade can be reduced by installing a splitter. The fan performance is successfully improved by controlling the chord length of the splitter installed near the blade suction side. Under the designed flow condition, the efficiency and pressure of a fan with splitters increase by up to 4% and 18%, respectively, compared to the reference fan.
