The paper is focused on studies of particle's path deflection near the wall. Particle is modeled by a rigid sphere suspended on the thread. A specially designed rig has been constructed where systematic experiments were done to obtain sphere trajectories for its three different sizes. Mathematical analysis led to correlation describing the influence of wall on particle movement in function of initial distance of the sphere to the wall and its Reynolds number. The analysis was based on original model postulated by authors. Comparisons of experimental data against correlations available from literature shows a satisfactory agreement.
