Digital holography is applied to study the particle distribution in boundary layer. A non-uniform distribution of particles with the peak value in logarithmic region With an increase of particle, the peak of the distribution moved toward the wall. As the airflow velocity decreased, the peak moved toward the channel centerline. The rotational velocity of particles is several hundred rotations per second.
