Body (2D) consists of 3 layers:
1. lower - crystalline hydrates (the assumption - water or ice)
2. medium - porous material (in the assumption - pairs)
3. upper - steel, with bore

The boundary conditions at the boundary of the body is given by convection to the environment with a temperature of 1100 C and the heat transfer coefficient. Inside the thermal protection - the adiabatic condition on the sides - the conditions of symmetry. For gas exit hole defined condition pressure outlet with a constant pressure.The initial conditions: the distribution phase, the rate of 0 and 20 C uniformExposure time - 1:00.

Process models: the laminar flow regime, thermal effects, multi-phase processes, phase transformation. Specify the conditions when the phase transformation temperature of 100 C.

Questions: about the models, there is the model of Euler? transformation phase is set by species? and how to set the conditions for the conversion phase and the initial distribution of the zones (at the initial time of 1 layer of water 100 per cent, a pair of 0)?
Thank you.

A picture is worth thousand words! Can you post your domains, BCs and then ask the question again, more clearly?
