This paper presents the results of measurements of the solid particle concentration field near a frontal point of a cylindrical body with a flat end. We restore the particle concentration fields based on their image identification obtained by photographic fixation at low shutter speeds. The experiments revealed the effect of increasing the particle concentration near the body surface, which appears more clearly with the increase in the local particle concentration in the oncoming flow. We analyze the mechanisms of the particle concentration increase in the flow around bodies by flows containing particles.
