Simulation of Reactive Chemical Transport in a Varying Thermal Field with Reaction-Flow Coupling

by C. L. Carnahan, Lawrence Berkeley Lab, United States,



Document Type: Proceeding Paper

Part of: High Level Radioactive Waste Management 1990

Abstract:

A computer program, THCVP, simulates coupling between advective/diffusive solute transport and chemical reactions, coupling of the reactions to heat transport, and feedback from precipitation/dissolution reactions to fluid flow. A simple simulation of transport of dissolved silicic acid along a gradient of temperature shows how precipitation of quartz at low temperatures can drastically reduce advective transport of all solution components including trace contaminants.
