Conclusions
-
1.
The experimental investigations of the interaction of a bore with an expansion in a certain range of variation of ho/Ho showed that the theoretical flow schemes are completely realized.
-
2.
The theoretical solutions obtained agree satisfactorily with the results of the experimental investigations and can be used for preliminary estimations of the values of the depths and cross-sectional average velocities at characteristic sites.
