THE PHYSICAL MODEL OF GEOTHERMAL WELL

Two-phase flow plays a predominant role in various industries especially geothermal reservoirs model, wellbore, and pipelines. The flow combines of phases which are gas/liquid, gas/solid, liquid/solid and immiscible fluids. The flow model can provide the fluid properties such as the temperature profile, the pressure gradient, and flow pattern. Due to the flow in the production well was evaluated the flow characteristics of the vertical pipe. The flow pattern in vertical upflow pipe is showed in the figure 3.
