内容記述 It is shown that a same equation on the vorticity in flow is derived from both axisymmetric theory and secondary flow theory, but the value of trailing vortex or streamwise vorticity cannot be obtained from this equation. The condition which decides the strength of trailing vortex in axisymmetric theory is expressed by the flow equation downstream of blade row. In the case of secondary flow theory, the strength of trailing vortex is decided from the boundary condition of the Trefftz plane at the exit of blade row. The latter coincide with the former at the limit of pitch → 0. In the case of axisymmetric flow, provided the exit angle of blade row being of free vortex type, we get the result that the streamwise vorticity is zero in the downstream of blade row. Th.is means that there exists no secondary flow in the downstream. The same thing is applied on the straight cascade. Because this result seems to be curious, verifications were tried from other angles.
