Solidification behavior can be altered by electromagnetic stirring,mechanically rotary stirring or uniform rotation of crucible under unidirectional solidification condition.
在定向凝固条件下,通过施加电磁搅拌、机械旋转搅拌以及匀速旋转坩埚等外力作用,可以改变金属的凝固行为,结果表现为生成不同的分层组织,而且对组织的细化程度、层片间距也产生不同的影响。
The effects of crystal rotation, crucible rotation and the combination of crystal rotation and crucible rotation on the melt convection, oxygen transportation, turbulent kinetic energy and turbulent viscosity were studied.
本文采用紊流模型对提拉大直径单晶硅时,对晶体旋转、坩埚旋转及二者共同作用三种情况下,熔体内的流线、等温线、氧的浓度分布、紊流粘性系数、紊动能等作了数值模拟,发现晶体的旋转能提高氧的径向均匀性,紊流粘性系数和紊动能随着坩埚转速的提高先增加后下降。
The stability of the Ekman flow during ACRT (accelerated crucible rotation technique) process, and the effects of the crucible diameter Φ, the maximum variation of the rotation speed, △ωmax , as well as the liquid height H in the crucible on the Ekman flow,were studied with hydraulic analogue experiments.
