文摘
- •
The D3Q19 lattice vectors are proposed to capture S/L interface advancement.
- •
Solidification entropy is defined to characterize quantitatively dendritic growth.
- •
Tip-splitting occurring at a fast solidification rate can be predicted by the model.
- •
A design map to predict dendritic growth with/without tip-splitting is presented.
