Abstract

Regarding the axisymmetric flow through an axial-flow turbo-machine, the radial equilibrium theory and the actuator disc theory have been expounded, in which the effects of impeller breadth and blade shape have not been considered. In this paper a method is presented, in which the above mentioned disadvantages are eliminated. To the axisymmetric flow through a turbo-machine of the free vortex type, the author applies the fundamental partial-differential equations derived from the equations given by Lorenz and Bauersfeld, and the following cases are treated. (1) The flow through an impeller at the off-design point is treated on the assumption that the flow in front of the impeller is potential one, and numerical examples are shown. (2) The flow through an impeller at the design point is treated on the assumption that the flow in front of the impeller is inviscid shear flow, and it is shown that the flow in the rear of the impeller has a more uniform axial-velocity distribution.
