| Research Abstract |
The effect of the inlet guide vane on the performance of the cross-flow fan was examined. By installing guide vane in the suction region, the performance of the cross-flow fan becomes more high pressure and high efficient than the case without the guide vane. The prerotation of the inlet flow which is counter directional with the rotation of the rotor is generated by the guide vane. In the high flow region, the high pressure and high efficiency are obtained since the suction cascade work increases by the orerotation of the flow, and since the leading edge separation of the suction cascade is more avoided to high flow. Moreover, in the flow region, it is possible to suppress the circulating flow in scroll side in the rotor suction inlet. Therefore, the high efficiency is obtained in the low power compared to the results without the guide vane
