Experiments with Waiwera, a new geothermal simulator

摘要: In a companion paper we discuss the development of our new geothermal simulator, called Waiwera, and present results of tests on benchmark problems. In this paper we discuss the application of Waiwera to natural state simulations with models of Ngawha (New Zealand) and System B. These two models were chosen because they both involve mixtures of water and a non-condensible gas (carbon dioxide for Ngawha and air for System B) and they both have large contrasts in permeability. As a result the models run badly with a standard version of TOUGH2.
