摘要：

The effect of additional blades mounted on end limiting surfaces upon secondary flows in channels between blades in straight turbine cascades with large relative spacings and angles of flow discharge and with different initial vorticities was investigated experimentally. The optimal height of supplementary blades having a maximum effect was determined. Approximation formulas are derived permitting evaluation of the effects of supplementary blades in cases of varying inlet flow vorticity.
