Conclusions
-
1.
It has been shown that in canals of rectangular cross-sectional shape, the vector of the full turbulence stresses forms with the flow direction an angle equal to 65°, and the value of this angle does not depend on the distance to the solid boundary.
-
2.
It was demonstrated that the shearing stresses are proportional to the vector of the full turbulence stresses and that the proportionality coefficient is constant.
-
3.
We established the type of relation of the velocity gradient with respect to the vector of the full turbulence stresses, which is correct to the limit of the external layer in canals with rectangular cross-sectional shapes.
-
4.
A new equation is proposed for calculation of the velocity gradient in canals by means of the vector of full turbulence stresses.
