NIMFA SOFTWARE PACKAGE: SOLVING NONLINEAR SINGLE-PHASE FLUID FILTRATION AND HEAT-AND-MASS TRANSFER PROBLEMS IN POROUS MEDIA
The paper describes the NIMFA software package and an approach to solving the equations of nonlinear single-phase fluid filtration and heat-and mass transfer in porous media. The primary equations for the simulated processes and the equation discretization methods are presented. A verification matrix for 21 tests is given. It is shown that there is a good qualitative and quantitative agreement with analytical tests and results of simulations by third-party solvers.
