【摘要】根据非稳态傅里叶热传导方程及微结构光纤(MSF)预制棒的初始条件和边界条件,建立圆柱形坐标系,推导出MSF预制棒的温度场分布方程.计算结果表明:当MSF预制棒在高温炉内的温度场分布接近热传导稳态分布时的下棒速度为制备MSF的最佳速度,此时高温炉的加热温度可降低到MSF预制棒的软化温度,另外,随着MSF空气填充率的增加,MSF预制棒的下棒速度也应加快.更多还原

【Abstract】 Drawing temperature is an important factor affecting the structure of microstructure fibers (MSF) during MSF drawing. According to the Fourier equation of time-dependent heat conduction with, original conditions and boundary conditions of MSF preform, the temperature distribution equation of MSF preform is derived in cylindrical coordinates. It is shown the feeding speed of MSF preform is optimal when the temperature distribution of MSF preform is close to the steady-state heat conduction in high temperature furnace, then the temperature of high temperature furnace can be lowered to the intenerate temperature of MSF preform. In addition, the optimal speed will be increased if the air-filling fraction of MSF preform is high.更多还原
