ThermophysicalTransportModels: Added temperature gradient based heat flux models

Browse Source 
Fourier, eddyDiffusivity and nonUnityLewisEddyDiffusivity thermophysical
transport models now apply an implicit energy correction to a temperature
gradient based heat-flux to provide computational stability and efficiency while
converging to temperature gradient based solution.  This ensures consistent heat
exchange between fluid and solid regions in CHT cases and with heat-flux
boundaries.

The Fourier and eddyDiffusivity models support single specie systems only
whereas nonUnityLewisEddyDiffusivity supports specie diffusion with independent
specification of turbulent Prandtl and Schmidt numbers, i.e. non-unity Lewis
number.

The unityLewisFourier and unityLewisEddyDiffusivity thermophysical transport
models use an implicit energy gradient based heat-flux which is optimal for
numerical stability and convergence but does not guarantee consistent heat
exchange between fluid and solid regions and heat-flux boundaries in the
presence of gradients of heat capacity.  Both of these models support specie
diffusion with the restriction that the laminar and turbulent Prandtl and
Schmidt numbers are equal, i.e. unity Lewis number.

The thermophysical transport model is specified in the optional
thermophysicalTransport dictionary; if this file is not present the
unityLewisFourier model is selected for laminar and unityLewisEddyDiffusivity
for turbulent cases for backward compatibility.

The chtMultiRegionFoam tutorial cases have been updated to use the most
appropriate of the new thermophysical transport models.

Foam::turbulenceThermophysicalTransportModels::nonUnityLewisEddyDiffusivity
Description
Non-unity-Lewis-Eddy-diffusivity based gradient heat flux model for RAS or
LES of turbulent flow. Allows independent specification of turbulent
Prandtl and Schmidt numbers. The laminar Lewis number is still assumed to
equal one.
Non-unity-Lewis-Eddy-diffusivity based temperature gradient heat flux model
for RAS or LES of turbulent flow. Allows independent specification of
turbulent Prandtl and Schmidt numbers. Unity laminar Lewis number is
assumed.
The heat flux source is implemented as an implicit energy correction to the
temperature gradient based flux source. At convergence the energy
correction is 0.
