Laminarization of a boundary layer on the perforated surface with blind damping cavities in an accelerating flow

In this paper, a decrease of turbulent pulsations of velocity in a boundary layer and the coefficient of friction drag for an accelerating flow on the perforated surface with blind damping cavities is experimentally found. We generalize the mathematical model of partial boundary layer laminarization 1], which is based on the experimental data 2, 3] obtained earlier on a decrease of the friction drag coefficient and deformation of average velocity profiles in the stabilized section of flow in the perforated tube with blind damping cavities.
