CONCLUSION

1. The model of BO-3 is capable of the two-phase modeling with a various friction, friction correction factor and void fraction correlation
 
2. The predicted temperature shows that it can achieve the saturation phase  at temperature above 250 C

3. A measure of each void fraction performs in simulating the pressure and temperature profile  shows the uncertainty analysis and sensitivity.

4. Inaccurate prediction can be caused by the use of physical properties of water that do not represent actual thermodynamic behavior of geothermal fluid
