Include short-term effects in sizing

wouterpeere commented 1 year ago

Right now, GHEtool ignores the internal capacity of the borehole, by making use of the equivalent borehole thermal resistance. This short-term effects however, can play an important role in some cases.

A resistance-capacitance model can be implemented like the one from (Minaei and Maerefat, 2017).

A first short-term effect (cylindrical correction) was added in issue #187

Validation will done on two levels

[ ] Inter software tool (and other GHEtool methods) comparison based on #243
[ ] Dynamic simulation model (ibpsa modelica borehole model)

Next steps should focus on the following improvements:

[ ] Develop a more general method for determining the far field radius that is applicable to non-rectangular shapes.
[ ] Calculate the fluid factor based on the borehole configuration.
[ ] Extend the numerical model to be able to handle double u-tubes

The sensitivity analysis should consider the following parameters:

[ ] Borehole spacing
[ ] The num_intervals parameter in the numerical model
[ ] Time step used in numerical model
