In recent experiments of translating droplets, results have indicated that there may be a unique source of vorticity located at the triple contact line or corner singularity. In this paper, vorticity generation at sharp corners is identified and characterized by investigating a small region near the corner where the Reynolds number is small and Stokes flow assumptions are valid. Specifically, the flows described by a stream function of order r and constant interface velocity are investigated. For this class of flow, it is determined that the vorticity near the corner singularity scales with r~(-1) and expresses a dipole vorticity distribution with a point source of vorticity at the corner singularity. The vortex dipole is created by a jump in the interface velocity or direction at the sharp corner. Analytical relations are provided for predicting the strength and orientation of the dipole. A comparison of the analytically predicted dipole vorticity distribution shows good agreement with independent Navier-Stokes simulations of the paint scraper problem.
