The objective of this study is investigate the flow performance analysis with various housings of an electric fan with counter-rotating fan. The housing of an electric fan serves as a guide for flow and has the effect of increasing flow straightness. Because of this advantage, the counter-rotating fan is designed to be used for ventilation purposes. The housing shape was modeled by selecting the radius of curvature as parameter. In this paper, the internal and external flow characteristics and performance of the counter-rotating fan were analyzed through CFD results according to the radius of curvature of the housing.
