摘要：

A phase-field model(PFM)coupling with phase field,flow field and diffuse equation is presented for simulating isothermal dendrite growth of a nickel-copper alloy under a forced flow.Based on the finite difference method with uniform grid,the C programming code is implemented to complete the phase-field simulations.The simulation results indicate that the interfacial morphology,the symmetry of dendrite formation,the tip growth velocity and the concentration distribution are strongly influenced by the fluid flow.
