Abstract
Solute transport in fluids can be simulated with Lagrangian methods such as Random Walk Particle Tracking(RWPT). These methods are virtually free of numerical dispersion and instabilities, which makes them particularlywell-suited to advection-dominated problems, and hence an attractive alternative to Eulerian approaches. However,incorporating nonlinear reactions in random walk models is not a straightforward task, since solute concentrationsare not readily available. A simple appr...
