提出了一种对多孔介质中多组分反应输运控制方程进行变换的方法。通过解耦方程和消除未知量，简化了问题的求解，提高了数值模拟的效率。这里提出的重新表述是对早期工作的概括。事实上，现在呈现了一整套的转换。这个类是通过选择某些变换矩阵来参数化的。对于特定的选择，可以检索一些已知的反应传递公式。因此，基于所提出的转换的软件可以用来获得不同求解方法的效率比较。对于我们的效率测试，我们在无功传输上使用MoMaS基准问题。
We present a method to transform the governing equations of multispecies reactive transport in porous media. The reformulation leads to a smaller problem size by decoupling of equations and by elimination of unknowns, which increases the efficiency of numerical simulations. The reformulation presented here is a generalization of earlier works. In fact, a whole class of transformations is now presented. This class is parametrized by the choice of certain transformation matrices. For specific choices, some known formulations of reactive transport can be retrieved. Hence, the software based on the presented transformation can be used to obtain efficiency comparisons of different solution approaches. For our efficiency tests, we use the MoMaS benchmark problem on reactive transport.
