Research on the Axisymmetric Flow through an Axial-Flow Turbo-Machine : 2nd Report, Axisymmetric Flow at Design Point in Multistage Turbo-Machines of Various Vortex Types

抄録

In this report, the author has treated the axisymmetric flow at design point in multistage turbo-machines of various vortex types, such as the constant reaction type and the exponential type, using a similar method to that described in 1st Report. Regarding the axisymmetric flow through an axial-flow turbo-machine, the radial equilibrium theory and the actuator disc theory have been expounded, but the effects of impeller breadth and blade shape have not been considered in these theories. The method described in the present paper takes these effects into account. Numerical examples are shown comparing the results calculated on the basis of the above mentioned theories.
