Abstract

Extensive tests on the Vortex Wind Tunnel fitted with sand
cast blades of free vortex design, have been carried out.
The performance of the blades is much better than obtained in
previous tests (Ref. 3) and this is attributed to modifications made
to the tunnel.
Whenever possible, the results from the tests are compared
with two dimensional cascade data (Refs. 4, 6 and 15), and radial
equilibrium studies are made on the flow. The agreement between the
actual blade performance and the cascade data, is good, considering
that the blades themselves are not of design shape. The flow appears
to have almost reached a state of radial equilibrium-i chord lengths
downstream of the blade rows.
By examining data on secondary flows, (Ref. 10, 11, 16 and
17), and results from the Vortex Wind Tunnel, a picture of secondary
flow formation is presented.
