A two-dimensional(2D) cellular automaton-lattice Boltzmann(CA-LBM) model was employed to simulate the dendritic growth in the presence of forced convection during isothermal solidification of binary alloys.In the model,the dendritic growth is simulated by a CA approach,and the flow field and the concentration field are numerically solved using the LBM based on the gas kinetic theory. The model was applied to simulate the single dendritic growth of Al-Cu alloys in the cases of pure diffusion and melt convect...
