Description

This example demonstrates MUFITS capabilities for numerical modelling of the mechanical (hydrodynamic) dispersion in porous media. The longitudinal and transverse dispersion of the solute and temperature can be simulated together using the same simulation option. The input data to 4 benchmark examples which allow exact solutions are provided and are used for validation of the simulation option. First two benchmark are examples of dispersion of solute transport in porous media while the second two benchmarks are examples of temperature dispersion in a non-isothermal flow. The 1D benchmarks are intended for the validation of the longitudinal dispersion whereas 2D benchmarks are intended for the validation of the transverse dispersion. In order to reduce numerical dispersion the flows are simulated using refined grids and with a small timestep.
