GENERALIZATION OF THE SEMI-EMPIRICAL THEORY OF TURBULENCE TO FLOWS NEAR ROUGH SURFACES WITH VARIOUS MODES OF ROUGHNESS

Turbulent flow near a wall is considered. On the basis of experimental data, a new concept is introduced-a sublayer near the wall-and a universal two-layer model of the motion is assumed that is valid for turbulent flow at smooth and rough walls. From this, and using Prandtl's semiempirical theory of turbulence, is set up a generalization to flows as surfaces with arbitrary roughness properties. As a result, new and unique relationships are defined for computing the flow near walls with arbitrary surface roughness and for all stages of its manifestation.
