　　For 1D and 2D elastic-plastic flows with the hypo-elastic constitutive model and von Mises yielding condition,the non-conservative character of the hypo-elastic constitutive model and the von Mises yielding condition make the construction of the solution to the Riemann problem a challenging task.

除尘管道粉尘运移及沉积研究

采用欧拉–拉格朗日方法，并考虑气相与颗粒相的双向耦合，对管道内不同工况下气固多相流动进行了数值模拟。基于颗粒与壁面碰撞过程中的能量分析，建立了粉尘沉积–回弹模型，即粉尘颗粒与壁面碰撞后，法向速度所对应的动能大于壁面的黏附能才会回弹，否则会被壁面捕获。由此得出了粉尘颗粒的沉积准则以及颗粒碰撞后的回弹速度。
