Escape Kinetics of Self-Propelled Janus Particles from a Cavity: Numerical Simulations

摘要: We numerically investigate the escape kinetics of elliptic Janus particles from narrow two-dimensional cavities with reflecting walls. The self-propulsion velocity particle is directed along either their major (prolate) or minor axis (oblate). show that mean exit time very sensitive to cavity geometry, shape and strength. found be a minimum when length equal size. also find optimum as function velocity, translational diffusion, shape. Thus, effective transport control mechanisms for in channel can implemented.
