摘要
采用先进的光纤光栅传感技术,对经典的一维圆筒渗透模型进行了渗流场与温度场的监测,研究了渗流发生过程中介质的温度变化规律。研究结果表明:相同渗流水温时,随着渗流量的增加,渗透发生前后,介质温差相应增大,其增大值基本呈线性增大;随着渗流水温的增加,渗透发生前后,介质温差明显增大,其最大温差值为5.06℃。
By the advanced fiber Bragg grating sensor technology, the seepage field and temperature field were monitored to one-dimensional cylinder seepage model, some discipline Which occurred in the process was produced. Conclusions： on the condition of same seepage water temperature, the temperature difference is enlarged sharply like a linear increase with the increase of seepage quality. And the maximum temperature difference before and after penetration is 5.06 ℃ with the rise of the seepage water temperature.
