一、叶片前的弯曲通道和叶片前缘附近的速度分布 斜流风机(见图1)叶轮内的流动情况介于轴流风机与离心风机两者之间,可以近似看成沿一簇迴转面的流动,其特点在于沿空间三个方向的速度分量在数值上是可以比拟的,任何一个分量都不能忽视从而更带有三元流动的特点. First, the curved front of the blade and the blade near the leading edge of the speed distribution Diagonal flow fan (see Figure 1) flow within the impeller between the axial flow fan and centrifugal fan between the two, can be approximated as a cluster of rotation Surface flow, which is characterized by the velocity component in space along the three directions are comparable in value, any one component can not be ignored and thus more with ternary flow characteristics.
