摘要

We apply a nonlinear reaction-diffusion-advection model to the simulation of a five-spot in-situ solution mining operation. The simulation is based on a finite element model of the governing equations. The porosity dependency of the hydraulic conductivity gives rise to a positive feedback, manifesting itself in porosity fingering instabilities. The deformation dependency of dispersion coefficients is also taken into consideration. Through the simulation, we demonstrate that the characteristics of mineral recovery concentration histories are affected significantly by the total injection flux or by the total ejection flux. The peak mineral recovery concentration decreases as the total injection or ejection flux increases.
