Numerical modeling of glacier flow
Application ID: 1761
Glacier ice is generally treated as an incompressible, heat-conducting non-Newtonian fluid. The viscosity of ice depends on temperature and on the state of deformation.
In the case of Storglaciären, however, the influence of temperature-dependent viscosity on the general flow field of the glacier is small. With COMSOL Multiphysics, it is relatively easy to verify that neglecting this temperature-dependence is justified.
