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.
