A numerical simulation infrastructure capable of calculating the flow of gas
and the trajectories of particles through an aerodynamic lens injector is
presented. The simulations increase the fundamental understanding and predict
optimized injection geometries and parameters. Our simulation results were
compared to previous reports and also validated against experimental data for
500 nm polystyrene spheres from an aerosol-beam- characterization setup. The
simulations yielded a detailed understanding of the radial phase-space
distribution and highlighted weaknesses of current aerosol injectors for
single-particle diffractive imaging. With the aid of these simulations we
developed new experimental implementations to overcome current limitations
