DEVELOPMENT OF ANALYTICAL MODEL AND NUMERICAL ANALYSIS FOR SPIRAL COIL TYPE GROUND HEAT EXCHANGERS

Full Article:

A spiral coil source model and its analytical solution was developed to consider 3-dimensional shape effects and radial dimension effects of a spiral coil type ground heat ex-changer (GHE) using Green’s function method. The spiral coil source model was transformed into a formula of error function to improve and simplify computation for the engineering ap-plication. To analyze the characteristics of the analytical model, the analytical model''s pre-diction results were compared with numerical analysis results implemented in ABAQUS/Standard.
