Geothermal systems are very complex. Apart from the Hydrogeologie systems, these systems include phase change and heat flow. Consequently, its very difficult to suggest variation depend on the discharge and recharge relation in such a complex, system. In this stage, modeling approach is obtained very important role to put forward the future state of the system,. Many advances in simulating fluid flow and heat transport in porous media have recently been made parallel to geothermal energy research.. These models are used to verify and improve conceptual models of geothermal systems.. The main goal of the modeling of geothermal systems is to provide answers to* important problems about potential of reservoir and injection effects. In this paper, a. summary of heat transport modeling in geothermal systems presented and the governing equations for heat flow briefly described

Anahtar Kelimeler

Jeotermal Sistemlerde Isı Taşınımının Modellenmesi

Öz

Jeotermal sistemler, oldukça karmaşık bir yapıya sahiptir., Bu. sistemlerde,, hidrojeolojik sistemlerden farklı olarak faz değişimleri ve ısı taşınımı da söz konusudur.. Dolayısıyla, böyle karmaşık bir sistemde beslenme-boşalım ilişkisine bağlı olarak meydana gelebilecek değişimleri öngörmek oldukça zordur. Bu aşamada, modelleme yaklaşımı sistemin geleceğine ilişkin bir öngörü yapabilmek açısından büyük bir önem kazanmaktadır. Son yıllarda matematiksel modeller yardımıyla jeotermal alanların niod.ellen.mesi yoğun olarak çalışılan, bir konudur.. Bu modeller, jeotermal alanların kavramsal modellerinin geliştirilmesi ve doğruluğunun kanıtlanması için kullanılmaktadır., Jeotermal sistemlerin modellenmesiode esas amaç, rezervuar potansiyelinin belirlenmesi ve reenjeksiyonun sistem üzerindeki etkilerinin ortaya konması gibi önemli problemlerin çözümüdür. Bu çalışmada, jeotermal sistemlerde ısı taşınımının modellenmesine ilişkin yaklaşımlar1 kısaca özetlenmiş ve modelleme çalışmalarına temel oluşturan ısı taşınımı eşitlikleri verilmiştir.

Anahtar Kelimeler

Isı taşınımı, jeotermal sistemler, modelleme, sıcak su.
