Possible effect of flow velocity on thawing rock-water-ice systems under local thermal non-equilibrium conditions
Original language description
Climate change causes thawing of many permafrost regions, increasing the rockfall and landslide hazard when the cementing ice melts and slopes become unstable. The thermo-hydro-mechanical processes are strongly coupled and complex to describe in those intrinsic multi-phase systems. So far, thermal models often utilize the local thermal equilibrium approach, assuming that all three phases (solid rock or soil, liquid water and ice) are in thermal equilibrium. While this approach is very tempting due to its easy implementation, there are situations especially during thawing in which temperature gradients exist between the involved phases. In such cases, the local thermal equilibrium approach has to be replaced by the more complex local thermal non-equilibrium approach in which the thermodynamic state of each phase is described by its own temperature. In those models, the heat transfer between the phases is described explicitly in dependence of the heat transfer coefficient and the contact area. Paramete
