In wide angle diffuser, the increasement of cross-sectional area so rapidly cause possibly separate from the diffuser wall and forming areas of backflow. The flow characteristics of wide angle diffuser with guide damper was investigated for three kind of inclined angle($\alpha=7_{\circ},\;10.5_{\circ}\;and\;14_{\circ}$)of guide damper. Judging from the results, guide damper can be used as an effective means of improvement for diffuser performance and inclined angle of $\alpha=10.5^{\circ}$ was through to be the best among three cases.

In planar angle diffuser, the increasement of cross-sectional area so rapidly cause possibly separate from the diffuser wall and forming areas of backflow. The flow characteristics of planar angle diffuser was investigated for three kind of inclined angle. Judging from the results, wide planar diffuser can be used as an effective means of improvement for diffuser performance and inclined angle of diffuser was through to be the best among three cases.
