Phase Field Simulation of the Pure Material Dendrite Growth in a Forced Flow
The phase field method is effective in simulating the formation of solidification microstructure.Based on the phase field models of coupling flow field and noise field proposed by Tong and Beckermann,using finite difference method to solve control equation,apartly simulating the dendritic morphology under the condition of convection or none convection,and drawing the following conclusions after comparing the results:in the side,the dendrite will no longer be symmetrical under the condition of countercurrent and downstream,the dendrite tip grows faster with countercurrent than that of the latter,while the dendrite grows almost naturally in the vertical direction of convection.
