Automatic parameter estimation in the model of underground buffer and rock heater test
Original language description
We present an example of using an optimization algorithm for the automatic estimation of material parameters, as an extension of common back-analyses of laboratory and in-situ experiments. The data used are from ?buffer/container experiment? in Canadianunderground laboratory. We use our own coupled heat and moisture transport model (ISERIT code) and the free parameters calibration program UCODE from the US Geological Survey. The optimization problem is solved for the simpler case of steady-state heat conduction. We present different cases of fixed and optimized parameters sets, some where the fit can be significantly improved with physically realistic parameters (small change from literature value) and some with non-convergent algorithm or physicallyunrealistic parameters in the optimum.
