| Abstract | This paper describes a mathematical model of geothermal processes in a significantly heterogeneous geological environment. The model is based on a mixed-hybrid formulation of finite elements and it has been implemented in our simulation code and prepared for putting through capability testing. The model is able to simulate subdomains of different dimensions. In this way, important fractures and fractured zones coupled with the regional extent of the simulated domains can be involved. Results of some model tasks are presented to demonstrate the behaviour of the model. As examples of real applications The Melechov massif (Central Europe) and Cajamarca (Peru) sites have been selected. Geology and hydrogeology of both localities have been studied. Conceptual models and computational meshes have been prepared on the basis of the real data. Physical properties have been specified according to geological properties. The real applications involve underground flow modelling as well as heat transport modelling for the case of pumping underground water. |
