Our simulations include thermal fluctuations and hydrodynamic interactions, which are both relevant for the dynamical behavior at nano-to micro-meter length scales. In order to investigate the importance of hydrodynamic interactions, we also perform Brownian-dynamics-like simulations. In both cases, we find that self-propelled rods display a strong surface excess in confined geometries. An analogy with semi-flexible polymers is employed to derive scaling laws for the dependence on the wall distance, the rod length, and the propulsive force. The simulation data confirm the scaling predictions.
