Abstract
In an airlay process thousands of fibers are distributed by a turbulent air stream to produce a nonwoven. We present models and numerical strategies in order to simulate the dynamics of the fibers until they are laid down to a conveyor belt. In particular, we focus on the effect of the turbulent air flow onto the fibers and their contact with walls. The simulation results of the laydown can be used further, e.g., as input for fiber laydown models in nonwoven production processes.
