Original Abstract

The contribution is aimed on the study of a tail, which is occurred in the draft tube of a turbine, when turbine is running out of its best efficiency point. The equation of the tail in Lagrange's coordinates are introduced. The shape of a tail is studying, on the basis of mathematical model, in dependence of specific energy. The conditions of stability of the tail are derived with dependence of boundary conditions.
