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$\approx 2.2·{10}^4$ 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 $t\le 2.5$ s near the jet's entry $(x/h>0.2,y/h<0.15)$, both models predicted local $\varphi$ values similar to the experiments. While at $t=2.5$ s, only the mixture model predicted the jet's bend with $\varphi \approx 0$ 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($\sim$10).

与错流的单液和液-液射流相比（JICF），很少研究液-固两相JICF。已经开发出一种实验装置来研究Re处水湍流横流中的液固混合物的垂直射流$\approx 2.2·{10}^4$超过4 s的时间。刚性微粒以水平纯水湍流垂直注入。喷射轨迹，穿透力和颗粒浓度是通过具有颗粒跟踪技术的高分辨率相机记录的。已经使用两种不同的欧拉模型进行了三维CFD模拟：商业代码中的两流体模型，以及在开源中开发的用于预测流体动力学，射流轨迹和颗粒传输的新型混合模型求解器。修改后的$ķ-\epsilon$ 模型（用于粒子诱发的湍流和湍流扩散），以及改进的浮力-$ķ-\epsilon$商业和开放源代码分别采用了这种模型。在$Ť\le 2.5$ 在飞机入口附近 $（X/H>0.2，ÿ/H<0.15）$，两个模型均会预测本地 $\varphi$值与实验相似。在$Ť=2.5$ s，只有混合模型可以预测射流的弯曲 $\varphi \approx 0$ 在区域 $（X/H>0.2，ÿ/H<0.15）$和实验中一样 混合模型构成了一个很好的折衷方案，以进行悬架JICF的全局预测，其计算量减少了O（$〜$10）。
