Navier-Stokes simulations are presented for two-way coupled, particle laden, two-dimensional mixing layers in the dilute regime. In contrast to previous numerical approaches for two-way coupled two-phase flows, the simulations are based on the vorticity, streamfunction formulation of the governing equations. While the fluid phase is treated in an Eulerian way, the particles are tracked in a Lagrangian fashion. The numerical approach is validated against simple test problems. Furthermore, the production/destruction of vorticity is shown to be related to the misalignment of the concentration gradient and the slip velocity, as well as to the difference in fluid and particle vorticities.
