Boundary‐layer behavior on continuous solid surfaces: III. The boundary layer on a continuous cylindrical surface

Abstract The behavior of laminar and turbulent boundary layers on a moving continuous cylindrical surface is investigated by the integral method, based on assumed velocity profiles that satisfy the appropriate boundary conditions. Equations for the characteristic boundary‐layer parameters are presented for both the laminar and turbulent boundary layers, and comparison is made with the boundary‐layer behavior over a cylindrical surface of finite length. The analysis for the laminar boundary layer with a logarithmic velocity profile leads to satisfactory results. The turbulent boundary‐layer behavior on continuous cylindrical surfaces, and cylindrical surfaces of finite length, can best be investigated experimentally.
