The influence of swirler vane with different installation angle on the premixed combustion flow distribution of axial swirler and radial swirler is searched with a numerical simulation method. the paper compares the axial swirler flow distribution and radial swirler flow distribution. The research results indicate, for the radial swirler, when the angle of the vane installation is 60°, the mixture propagates velocity along boundary layers is faster than the other three vanes installation, which can avoid flashback. For the axial swirler, the flow rate along boundary layers is in proportion to the vane installation angle of swirler in premixer. The radial swirler is much more helpful for reducing the length and size of combustor than axial swirler. This study can give a significant reference for the design of a premixer in premixed combustor.
