Motivation
The Temperature Flat Source Solution @model is one of the fundamental solutions of temperature diffusion equations modelling the temperature conduction in linear direction (see Fig. 1).
...
Subsurface Temperature Profile around Lateral Flow makes adjustments to Geothermal Temperature Profile
to account for the lateral reservoir flow with a constant temperature (see Fig. 1 and Fig. 2).
