摘　　要：对定向凝固Al-4.5%Cu(质量分数)固液界面前沿的流场和压力场进行计算,得出速度和压力分布图,并且分析了不同凝固速度对热电磁流体动力学效应的影响。The fluid flow and the pressure field in the front of solid-liquid interface of Al-4.5% Cu alloy（mass fraction） during directional solidification were calculated. The graphs of velocity and pressure distribution were obtained. The effect of different solidification velocity on thermoelectric magnet hydrodynamic effects was analyzed.
