摘要：

The results of an experimental evaluation of velocity profiles, turbulent pulsations, generation and dissipation of turbulent energy in a nonequilibrium boundary layer under the adverse pressure gradient are presented. The profiles of characteristics are estimated by means of the field dynamics of the two-component instantaneous velocity vectors measured by the optical method Smoke Image Velocimetry. The opportunities of using the field measurement method SIV to study the spatial evolution of small-scale characteristics in a boundary layer with a pressure gradient have been showed.
