Thermomechanical interaction between outer ice shells and deep oceans on icy moons of Jupiter and Saturn
Malík, Jiří ; Souček, Ondřej (advisor) ; Tůma, Karel (referee)
The thesis contains a survey of numerical tools for studying thermomechanical interactions of a two-phase system contained in a domain with an upper bound- ary that forms a free surface. The enthalpy diffused-interface formulation is used for an approximation of the phase change interface and the computing algorithm is benchmarked against an analytical solution of the Stefan problem. Arbitrary Lagrangian-Eulerian kinematical description of the continuum is applied to over- come the difficulty in the form of the free surface. The validity of the approach is examined on a thermal convection benchmark problem. 1
