Summary: In this paper we discuss upscaling of immiscible multiphase and miscible multicomponent flow and transport in heterogeneous porous media. The discussion presented in the paper summarizes the results of in “Upscaled modeling in multiphase flow applications” by V. Ginting et al. [Comput. Appl. Math. 23, No. 2–3, 213–233 (2004; Zbl 1213.76196)] and in “Upscaling of multiphase and multicomponent flow” by Ginting et al. (2006). Perturbation approaches are used to upscale the transport equation that has hyperbolic nature. Our numerical results show that these upscaling techniques give an improvement over the existing upscaled models which ignore the subgrid terms.
