Geoenergy Modeling I
This introduction to geothermal modeling deals with flow and heat transport processes in porous and fractured media related to geothermal energy applications. Following background coverage of geothermal resources and utilization in several countries, the basics of continuum mechanics for heat transport processes, as well as numerical methods for solving underlying governing equations are discussed. This examination forms the theoretical basis for five included step-by-step OpenGeoSys exercises, highlighting the most important computational areas within geothermal resource utilization, including heat diffusion, heat advection in porous and fractured media, and heat convection. The book concludes with an outlook on practical follow-up contributions investigating the numerical simulation of shallow and deep geothermal systems. Dr. Norbert Böttcher is currently working as a scientist at the Federal Institute for Geosciences and Natural Resources in Hanover, Germany. After his graduation in Water Supply Management and Engineering, Dr. Böttcher had worked at the Institute for Groundwater Management at Dresden University of Technology, Germany, as a lecturer and a research scientist. He received his PhD for developing a mathematical model for the simulation of non-isothermal, compressible multiphase flow processes within the context of subsurface CO2 storage. As a post-doc, Dr. Böttcher was employed at the Helmholtz-Centre for Environmental Research - UFZ in Leipzig, Germany. His research topics include numerical simulations and model development of geotechnical applications.
