Compared to single-liquid and liquid–liquid jets in crossflow (JICF), liquid–solid two-phase JICF is rarely studied. An experimental setup has been developed to investigate a vertical jet of liquid–solid mixture in water turbulent crossflow at Re over 4 s period. Rigid micro particles were injected vertically in a horizontal pure-water turbulent flow. The jet trajectory, penetration and the particles concentration were recorded via a high resolution camera with particles tracking technique. Three-dimensional CFD simulations have been conducted using two different Eulerian models: two-Fluid model in commercial code, and a new mixture model solver developed in opensource to predict the hydrodynamics, jet trajectory and particles transport. A modified- model (for particle induced turbulence, and turbulent dispersion), and a modified-buoyant- model have been employed in the commercial and open-source codes, respectively. At s near the jet's entry , both models predicted local values similar to the experiments. While at s, only the mixture model predicted the jet's bend with in the zone as in the experiment. The mixture model constitutes a good compromise for conducting global predictions of suspension JICFs at a computational cost that is reduced by a factor of the order of O(10).
