| Summary: | Utilization of geothermal energy is directly done by taking the heat to be utilized in various processes or mechanisms involving thermal energy. Heat extraction from a heat source to a fluid media (heat sink) uses a device known as a heat exchanger. <br />
<br />
<br />
<br />
Direct geothermal utilization usually uses a heat source from brine derived from the separator. In practice in the field, there are many obstacles in the utilization of brine, especially licensing from geothermal developers as well as technical problems in piping and scaling. In this research, a study one of the design of heat exchanger, Borehole Heat Exchanger (BHE) for geothermal utilization on geothermal shallow wells or wells that have not been produced. Design analysis is done using energy balance and mass to create a BHE model. The BHE model is also simulated using computational fluid dynamics (CFD). <br />
<br />
<br />
<br />
The design of BHE can help depend on the heat source of brine separator because the heat is taken directly from the rock. This design is expected to be developed in all places that have a temperature gradient above normal. |
