A Study on Characteristic and Internal Flow Condition in a Winnowing Fan

This paper describes the performance in the winnowing fan, which are used for head feeding type combines mainly used in Asia. The effects of blade angle and the bracket configurations at the inlet on the efficiency and internal flow conditions are experimentally investigated. The fan efficiency and...

description This paper describes the performance in the winnowing fan, which are used for head feeding type combines mainly used in Asia. The effects of blade angle and the bracket configurations at the inlet on the efficiency and internal flow conditions are experimentally investigated. The fan efficiency and the uniformity of flow along an axis are improved by reforming blade angle and bracket shape with holes. In addition, in this experiment we found that both of these two methods uniform the velocity distributions at fan exit and combination of these two methods make it possible to improve the fan efficiency in the limited design condition.
