Investigation of the behavior of reflected particles under conditions of heterogeneous flow past a blunt body: Experiment and calculation

“…Therefore, the results given in Fig. 2 correspond to the experimental conditions of [1]. The particle trajectory in Fig.…”

“…The points in Fig. 3 correspond to the experimental data of [1]. The experiment was performed at the incident flow velocity U x0 = 2.8 m/s, which corresponds to calculated curve 2.…”

“…In [1], we used a three-beam laser Doppler anemometer (LDA) by Dantec (Denmark) to measure the velocities of solid particles in the vicinity of the critical point of a body. Spherical glass particles of rated diameters d p = 50, 100, and 200 µm were used in the experiments.…”

“…5) Turbulent fluctuations of the velocity of air have no effect on the motion of particles. 6) In calculating the velocities of particles in collision with the body, the coefficient of velocity recovery is taken to be 0.8 [1].…”

“…This investigation is a continuation of the experimental study [1] where we obtained the velocity distribution for spherical glass particles of different inertia in the neighborhood of a body with a flat end. It is the objective of this study to perform calculations of trajectories of particles in the vicinity of a body, compare the results of calculations and experiments, and generalize the obtained data for a wide range of determining parameters.…”
