Evolution of a Geothermal System with Fluid Re-Injection

open access: yesApplied Sciences, 2020
In this paper, we study the stationary configurations of a vapor-dominated geothermal system. We propose a general mathematical model, which turns out to be a free boundary problem, and we focus on the stationary solutions.
