Abstract
Summary: This study describes newly developed mathematical models of bottle rinsing. Our approach is based on 3D‐CFD models of turbulent two‐phase flow (water and air), which have been implemented based on the freely available open source software OpenFOAM. The models are validated using data obtained with a standard injection nozzle and then used to evaluate the performance of two fictitious modified nozzle types w.r.t. cleaning efficiency, water consumption and water drainage. Maps of the interior walls of the bottles showing the distribution of important parameters such as wall shear stresses or water coverage were derived from the simulations. The simulations suggest that rotating or pulsating injection nozzles may perform better than standard nozzle configurations.Keywords
