Particle tracing techniques for flows in porous media
Abstract
A description is presented of the tracer-fluid method which shows a good potential for applications involving the modeling of flows through porous media in regimes where either the classical Darcy type calculations fail or the permeability is unknown. It is found that for the majority of practical porous flow problems, a statistical description of the media can be valid. The considered method is currently in its initial stages of evolution and will require additional development in several areas prior to becoming a working tool. The tracer particles considered by the method are hypothetical particles with properties such that they are free to follow the motion of the fluid through the porous media without interfering with the flow. The tracer properties are followed dynamically through the fluid using the Langevin equation.
