recordSmallScale_Configuration
Configuration data record for the Cimmino and Bernier (2015) experiment
Extends from Buildings.Fluid.Geothermal.Borefields.Data.Configuration.Template (Template for configuration data records).
Information
This record contains the configuration data of the Cimmino and Bernier (2015) experiment. Since the model is not adapted to the simulation of small scale boreholes, the borehole dimensions are multiplied by a factor 375 to obtain a scaled-up 150.0 m long borehole.
