Abstract: Capture on a vibrating cylinder is simulated. Flow field is obtained with lattice Boltzmann method combined multi-block lattice Boltzmann method. Motion of single particle is calculated with Langevin equation by Lagrange integration. Drag force and Brownian diffusion is considered only. Cylinder does harmonic motion in flow direction with various frequency and amplitude at Re=200. As a result, different flow pattern present. We found capture efficiency raises. Especially at AⅢ vortex pattern, distribution of initial position deviates from center.

Key words: lattice Boltzmann method, vibrating cylinder, particle capture, Lagrange tracking method
