Reactive Transport Modeling

Definition

Reactive transport modeling is a computational approach used to simulate the movement and chemical reactions of fluids within porous media. This modeling integrates fluid flow, heat transfer, and the geochemical interactions that occur between the fluids and the surrounding materials. It's crucial for understanding processes in geothermal systems, particularly how geochemical reactions affect fluid properties and behavior during geothermal energy extraction.
