| So, what we
have seen in today's lecture are a coupled volumetric liquid model based
on a mechanistic approach has been presented in terms of ground water flow,
which are temperature dependence, and you have a transient phenomenon and
the liquid transport and the vapour transfer they all can be coupled together
to give a realistic simulation and we also stressed the importance of thermo-physical
properties, because the hydraulic conductivity is quite a non-linear function
of ql,
which is, and also the capillary potential, which also are a non-linear
potential of ql. Therefore we need to measure those parameters experimentally, and we have also seen that the literature the variation has been quite non-linear for variety of soil conditions. And we also said that the mathematical formulation that we proposed has been validated with the results from heating experiment. |
