简述了单辊搅拌技术制备 2A11半固态材料基本原理·利用ANSYS有限元分析软件包中CFD14 1单元 ,对制备 2A11半固态材料过程中耦合场进行了数值模拟 ,得出了温度场与速度场的分布规律·在轧辊作用下 ,靠轧辊越近 ,合金液体层运动速度越大 ,离轧辊越远 ,液体层运动速度越小·在近轧辊处出现速度最大值 ,在近靴处出现明显的速度递减·由于轧辊的转动 ,使合金等温线发生偏移 ,近轧辊侧温度偏高·
The basic principle of 2A11 semisolid material was briefly described. The coupling field of 2A11 semisolid material was numerically simulated by using CFD141 element in ANSYS finite element analysis software package. The temperature field and velocity field The distribution of the law under the action of the roller, the closer the roller, the alloy layer of liquid moving faster, away from the roller, the smaller the velocity of the liquid layer at the near-roll speed maximum appears near the boot at the obvious Decreasing speed · Due to the rotation of the roll, the alloy isotherm is shifted and the temperature on the near roll side is high ·
