Finite-Element Model for Heat Conduction in Jointed Rock Masses

摘要

A finite-element model for heat conduction in fractured rock is described and illustrated. The numerical method employs a statistical description for the fracture network and its associated properties. The effects of open fractures on the heat-conduction process are implemented in the numerical procedure at the element level in the form of effective thermal properties for fractured rock. An example problem illustrates the type of conduction problems that can be simulated with the proposed method. (ERA citation 08:042451)
