In this paper, a numerical study of the convection effect on polycrystalline grain growth is performed. The coupled two-dimensional polycrystalline phase field model, energy equation and Navier-Stokes equations are solved, which is based on the discontinuous Galerkin finite element method. The numerical algorithm is validated, and the effect of the external convection flow is examined for growth of grains with different orientation. Results show that the forced convection flow affects the phase and orientation field distribution by changing the temperature gradient in the solid/liquid interface.
