Abstract
The results of an experimental investigation into the steady-state plane turbulent boundary layer in an incompressible liquid at an impermeable wall are presented. Cases of flow at smooth and rough surfaces in the presence of a longitudinal pressure gradient are considered. The results of measurements of the turbulent structure of the flow at various distances from the channel inlet are presented. A detailed analysis of the kinematic and dynamic characteristics of the flow is given. Special attention is paid to the boundary region of the flow close to the wall. A universal law is proposed for the variation in the local resistance coefficient along the boundary layer.
