Research the Effect of Forced Flow on Dendritic Growth with Adaptive Finite Element Method

Abstract:

Phase field model coupled with flow field is solved by the adaptive finite element method. The simulation results show that the forced flow can induce side-branches though there is no thermal noise. When the flow velocity is low, the symmetry of dendrite morphology is slightly influenced by forced flow. With the increase of flow velocity, the symmetry of dendrite morphology is collapsed completely.
