Special Issue Information

Dear Colleagues,

Our understanding of the transport and dispersion phenomena in natural fluid flows is gaining increasing relevance, as we are increasingly dealing with the issues of environmental management, particularly when trying to mitigate risks from natural hazards, pollution, and climate change.

In this frame, a suitable modelling of all the involved processes is essential to the reliable simulation and prediction of flows, which range from river to maritime hydraulics, from atmospheric flows to limnology.

The aim of the present Special Issue in Water is to present the state-of-the-art knowledge on the modelling of complex environmental flows, where fluid dynamics often couple with chemical and ecological process, as well as with the transport of particles, floating debris, or contaminants. Overviews of specific topics and of the future challenges in the related research areas are particularly welcome.

Digital rock images may capture more detailed pore structure than the traditional laboratory methods. No explicit function can correlate permeability accurately for flow within the pore space. This has motivated researchers to predict permeability through the application of numerical techniques, e.g., using the finite difference method (FDM). However, in order to get better permeability calculation results, the grid refinement was needed for the traditional FDM and the accuracy of the traditional method decreased in pores with elongated cross sections. The goal of this study is to develop an improved FDM (IFDM) to calculate the permeabilities of digital rock images with complex pore space. An elliptical pore approximation method is invoked to describe the complex pore space. The permeabilities of four types of idealized porous media are calculated by IFDM. The calculated results are in sound agreement with the analytical solutions or semi-empirical solutions. What’s more, the permeabilities of the digital rock images after grid coarsening are calculated by IFDM in three orthogonal directions. These results are compared with the previously validated lattice-Boltzmann method (LBM), which indicates that the predicted permeabilities calculated by IFDM usually agree with permeabilities calculated by LBM. We conclude that the presented IFDM is suitable for complex pore space. Full article
