Abstract
A review of most popular direct and indirect methods of skin friction measurement and their brief characteristic are given. A comparative analysis of measurement results is presented; the results were obtained using some of the methods in an incompressible turbulent boundary layer on a flat plate under conditions of the formation of a negative (favorable) streamwise pressure gradient on the plate surface and in a gradient-free flow. The degree of effectiveness of the methods under the conditions described is evaluated, and the limits of their applicability and limitations are shown.
