摘要

从阐述多孔介质传热过程出发，逐一分析了在非渗流及渗流情况下，光纤与多孔介质之间的传热过程，详细分析了光纤与水流对流的传热过程，推导了多孔介质中渗流水和光纤之间的换热系数计算公式。在一定假设条件下，推导了导热系数（渗流流速）、加热功率和温升的非渗流情况与渗流情况监测理论方程，为分布式光纤传感技术监测渗流的应用提供了坚实的理论基础。

Abstract

Starting with expatiating the heat transfer process of porous medium

heat transfer process between optical fiber and porous medium on non-seepage condition and seepage condition is analyzed one by one. The process of convection heat transfer between optical fiber and seepage is studied detailedly. The formulas of calculating heat transfer coefficient between optical fiber and seepage in the porous medium are deduced. Based on some hypotheses

the theoretical equation of seepage monitoring about thermal conductivity (seepage velocity)

heating power

and temperature rise are deduced

which offers the steady theoretical foundation for the application of this technology.
