The motion of a small particle in a twodimensional steady flow with an arbitrary velocity field
Abstract
The present study considers the motion of a small spherical particle in a twodimensional steady vortex flow under the condition that there is only a small difference between the particle velocity vector and the flow velocity vector. The angle between these vectors and the relative difference of the moduli of these vectors are studied in relation to the flow parameters, including the streamline curvature, the longitudinal pressure gradient, and vorticity. The analysis may be relevant to laser velocity measurements in gas flows.
