Jeotermal Sahalarda Fayların Eğiminin Ve Permeabilite Kontrastının Sıcaklık Ve Akış Dağılımına Etkisinin Sayısal Modellenmesi

The presence of faults/fractures in geothermal fields significantly affects fluid flow and temperature distribution. This effect is more dominant especially in areas with dense faulting. Previous studies discussed the effects of the faults and permeability contrast between faults and surrounding geological units on fluid flow. In order to investigate this phenomenon, numerical methods are unique since they include physical and hydraulic parameters of the medium. In this study, the temperature pattern and groundwater flow due to the dip angle of the fault and permeability contrast were explored by various 2-dimensional numerical test models. We used finite volume-based Computational Fluid Dynamic (CFD) Software, ANSYS Fluent, for numerical modeling. The results of the numerical simulations indicate that, although the dip angle of the fault can slightly modify the fluid vectors and temperature distribution, the main determining factor is the permeability contrast. This study can be used and expanded as a preliminary study to predict the possible fluid paths, in extensively faulted geothermal fields.
