Abstract:

In sharply turbulated streams to 30, the basic laws of streams with normal initial turbulence are preserved. Audomodelive velocity takes place along the length of the stream and rectilinearity of the isotachs. When calculating turbulized stream boundaries, it is necessary to consider the increase in pole distance from the cut of the nozzles with a rise in initial turbulence. When calculating range of turbulated streams, it is necessary, together with the change in the value s, to take into attention the increase in turbulence coefficient a with an increase in the intensity of initial turbulence. Experimental data are given of boundaries and long ranges of flat submerged streams, the initial turbulence of which varied from 6 to 30. Calculation of such flow is possible with the aid of semiempirical theory of turbulent streams at a corresponding selection of semiempirical constants. Given is a change in these constants with an increase in initial turbulence of the stream. Author
