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 approximate to 2.2.10(4) 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-k - epsilon model (for particle induced turbulence, and turbulent dispersion), and a modified-buoyant-k - epsilon model have been employed in the commercial and open-source codes, respectively. At t <= 2.5 s near the jet's entry (x/h > 0.2, y/h < 0.15), both models predicted local phi values similar to the experiments. While at t = 2.5 s, only the mixture model predicted the jet's bend with phi approximate to 0 in the zone (x/h > 0.2, y/h < 0.15) 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(similar to 10).
