The Thermal Conductance Of Collection Tubes
In Geothermal Energy Systems
Author(s)
R. L. Frederick & A. Zenteno
Abstract
The numerical simulation of heat transfer in geothermal heat exchangers is
performed. Systems consisting of horizontal tubes embedded in the ground are
simulated for time periods of 3 months. Cases comprise OF a single tube, two
parallel tubes and a horizontal array of 9 tubes. The thermal conductance
between tubes and soil is defined and numerically determined, and scaling laws
are formulated for its dependence on the main independent variables.
Interference between tubes in arrays is also characterized by an index relating to
heat transfer from a single tube. The design criteria for tube arrays is formulated.
Keywords: geothermal heat exchangers, thermal conductance, numerical model.
Keywords
