Abstract: Numerical simulations of the particle-vortex interactions for an unforced, incompressible, spatially developing horizontal particle-laden turbulent planar jet are reported. Effects of the initial two-phase velocity slip on the instantaneous concentration distribution of particles with and without the influence of gravity are studied. Continuous phase simulation is performed by the method of large eddy simulation (LES) while the particle phase is solved by a Lagrangian method. Extensive results on the particle-laden jet flow are obtained. Simulation of the gas-phase reproduces the essential features of the coherent structures in the planar jet. Length of the potential core and essential features of the coherent structures in the planar jet are compared with experimental and other theoretical results. The simulation shows that initial two-phase velocity slip plays an important role in enforcing particle transverse dispersion in the jet region and sharply changes the instantaneous particle distribution. Furthermore, results demonstrate the influence of gravity on particle dispersion and sedimentation. Such pronounced effect of gravity on instantaneous concentration of particles with increased Stokes number and initial slip coefficients emphasize the need for the consideration of gravity for horizontal particle-laden jet.
