Temperature dependent single phase thermal conductivity

[sytuannguyen]

This PR is part of the project for non-linear thermal constitutive behavior from TotalEnergies. It tackles the problem of linear temperature dependent single phase effective thermal conductivity of porous medium.

thermalConductivity = defaultThermalConductivity + dThermalConductivity_dT * (T - T_reference)

where defaultThermalConductivity, dThermalConductivity_dT and T_reference are given in the xml input. The existing linear model in GEOS corresponds to the particular case of a constant thermal conductivity, i.e. dThermalConductivity_dT = 0.

• [x] Implement the non linear thermal constitutive model
• [x] Update the thermal single phase flow with respect to non linear thermal behavior
• [x] Update xml files to add new inputs: dThermalConductivity_dT and T_reference
• [x] Integrated test
• [x] Unit test
• [x] Validation example: doc and Python script for validation
