User-supplied EoS-modules
Description
These examples demonstrate the possibility of MUFITS linking with user-supplied shared libraries, i.e., EoS-modules, for the phase equilibria and other fluid properties prediction. Both explicit correlations and tabulated data for the fluid parameters can be implemented in the libraries. An iterative approach, which for example is based on the phase equilibria calculation through the Gibbs energy minimisation, can also be used in the EoS-module. A considerable effort has been undertaken to minimise the number of program procedures exported by the shared library. This should facilitate and ease usage of the software extension by scientific community. Furthermore, we supplement the modelling option with the source code for a couple of simple EoS-modules that can serve as templates in different modelling and software development efforts. We apply these modules in the benchmark studies 1 and 2. The first study concerns a 1-D flow of a multicomponent gas and the second study involves two-phase flow of immiscible fluids. The EoS-modules are also useful for coupling MUFITS with other elaborate software for fluid properties prediction. To demonstrate such possibility, we supplement the article with the source code of a more complicated EoS-module that couples MUFITS with the geochemical code GEMS3K. This module is used in a simple benchmark study 3 showing MUFITS capabilities for modelling reactive transport in porous media. The details of this modelling option are given in the attached paper draft.
