Within a borehole a nozzle can be installed in order to increase the efficiency of fluid injection. The position of the nozzle is located near the perforated casing of an injection well. A COMSOL Multiphysics® model is set up for a typical nozzle design as applied in practice. The model is based on the Navier-Stokes equations with turbulence closures using k-ε model and k-ω closures. We find a better performance for the k-ω approach. For the practical application we show that the lowermost outlets are most important and should be placed accordingly for a most effective injection.
