| 摘 要： | 采用CFD软件对喷射成形工艺过程雾化室内金属颗粒的行为进行了模拟，研究了不同雾化压力下、不同粒径的金属颗粒运动轨迹及温度变化情况。模拟结果表明，随着雾化压力的增大，金属颗粒的运动速度明显增加，金属颗粒到达沉积器上的温降更加显著，且颗粒运动轨迹的锥形区域扩散角减小；在相同的雾化压力下，粒径较大的金属颗粒在雾化室内的飞行速度和温降速率明显小于粒径较小的颗粒。

| Abstract: | Numerical simulation was performed to study the behavior of atomized metal granules in spray forming by using the CFD software.And the movement and temperature of metal granules under different atomizing pressure and with different granule diameters were investigated.The results indicated that with the increase of atomizing pressure,the flight velocity of metal granules increased and the temperature of metal granules decreased obviously when falling onto the substrate,and a cone-shaped angle formed by diffu... |
