An adaptive scheme for the sequential formulation of reactive transport involving two fluid phases is presented. Instead of solving the transport problem on the global fine-scale model, we decompose the domain into coarse gridblocks that are aggregates of fine gridblocks, and we define and solve transport problem on each of the coarse blocks. The details of the prolongation operator that allows for accurate reconstruction of the fine-scale solution within a coarse gridblock are described. The prolongation operator is independent of the details of the chemical reactions involving the particular component being transported and does not interfere with the chemical module, providing flexibility of implementation and applicability to a wide range of conditions. Test cases include applications of the adaptive strategy for chains of homogeneous decay reactions, as well heterogeneous reactions that involve changes in porosity and the reactive surface area with variable time step size and changes in operational conditions.

提出了涉及两个流体相的反应传输的顺序公式的自适应方案。我们不是在全局细尺度模型上解决传输问题，而是将域分解为粗网格块，这些粗网格块是细网格块的聚合，我们在每个粗块上定义和解决传输问题。描述了允许在粗网格块内精确重建精细尺度解的延长算子的细节。延长算子独立于涉及被运输的特定成分的化学反应的细节，并且不干扰化学模块，提供实施的灵活性和对广泛条件的适用性。
