Numerical Simulation of the Temperature and Stress Field in the Rock Heating Experiment
Original language description
The presented work is motivated by pre-realization phase of rock heating experiment in underground, testing the rock properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with thegeo-polymer. We used the Heat Transfer Module and the Structural Mechanics Module in COMSOL for modeling of the transient heat conduction with thermo-elasticity in 3D, both with parametrized material properties. The objective of the work was to predict the temperature distribution and induced mechanical stresses in the area close to the heater, in order to set working range of sensors placed in measuring boreholes spread around the main borehole. The largest mechanical loading emerges on heater-geopolymer-rock interfaces, but the general shape of the temperature and stress field outside the borehole is mostly influenced by properties of the rock.
