and simulate both of the single and multi-grain dendritic growth of Ni-Cu alloys in a forced flow. The results show that the fluid flow alters the local heat and solute transfer at the solidification front, thus the dendritic growth behavior is significantly influenced. Under forced flow with a flow velocity of 6.43 m/s, the temperature and the concentration of the upstream dendritic crystal......
