Hairy structures are necessary entities to trap the particles in flow and has been analyzed hydrodynamically to account for this mechanism. Due to small size of the hairy structures, studies have been carried out with low Reynolds number fluid dynamics. In this work, flow structure and inertial particle dynamics along those structures are investigated numerically. Correlation between flow structures and inertial particle behaviors are analyzed in sense of the Stokes number, and particle kinematics is examined numerically. General particle behaviors along the moving structures are investigated by computing drift volume. Furthermore, paddle-like acting in low Reynolds number flow is also examined with flow structure analysis and particle tracking. An in-house developed immersed boundary method (IBM) code is used to produce flows near the structures, and particle dynamics is also investigated numerically using the Maxey-Riley equation.
