This model is about using geothermal power as a brine heater (steam source) for evaporation via direct vapor generation through the geothermal field. Flash evaporation tank is used to generate the heated brine from the geothermal well. The brine content from the flash tank is considered as a blowdown. Condenser unit is used for condensation process. Seawater or saline water will be pumped directly to the geothermal well. Free salt steam will be directly goes towards the condenser unit for condensation and fresh water production. Seawater will go first through the condenser unit for the cooling purpose of the extracted steam that coming from the geothermal well. Nanofilteration unit is added in order to reduce the salinity contents in the intake saline water. It will be considered as a pre-stage before the condenser unit. All auxiliaries will be powered via the main grid. The cycle contains the following:
1-Pump unit.
2-Nanofilteration unit.
3-Condenser.
4-Geothermal well. 
5-Flash evaporation Tank.
6-Cost analysis.
7-Power costs.
 
**MatLab-SimuLink should be used to run the model.
