The detail of physical formulation of surface heat balance
Hello, everyone.
I am now learning how EnergyPlus works by reading the source code of EnergyPlus after learning Engineering Reference.
Now I feel a little difficult about the calculation of heat balance in "CalcHeatBalanceInsideSurf2".
From L.6208 of 'HeatBalanceSurfaceManager.cc', there are equations to calculate the current surface temperature 'TempSurfInTmp' using 'TempTerm' and 'TempDiv'. I would like to understand how those are physically formulated but I think this is not mentioned clearly in Engineering Reference.
At the same time, about the Conduction Transfer Function, I can know what kind of the things happen by reading the Engineering Reference but I cannot understand where the parameters like construct.CTFSourceIn and construct.CTFCross are directly explained in the Engineering Reference.
Where can I find the detailed information about those equations?
I am very glad if I can find some papers and I can understand the detail of physical formulation of EnergyPlus.
