An investigation of the kinematic structure of a turbulent flow and the motion of solid particles in its bottom region

Statistical analysis (based on motion-picture data) of the paths of neutral­ buoyancy indicators and heavy particles (mean values and second-order correlation moments for the velocity components) is used to propose a three-layer model of a turbulent flow with solid particles in skipping motion in its bottom region. The presence of a concentration maximum of the solid particles at a fixed distance from the bottom of the flow is explained.
