The impact of microscale physics in continuous time random walks for hydrodynamic dispersion in disordered media
Xiangnan Yu, Marco Dentz, HongGuang Sun +1
The continuous time random walk (CTRW) approach has been widely applied to model large-scale non-Fickian transport in the flow through disordered media. Often, the underlying micro…

Distributed order Hausdorff derivative diffusion model to characterize non-Fickian diffusion in porous media
Yingjie Liang, Wen Chen, Wei Xu +1
Many theoretical and experimental results show that solute transport in heterogeneous porous media exhibits multi-scaling behaviors. To describe such non-Fickian diffusions, this w…

Fractional constitutive equation (FACE) for non-Newtonian fluid flow: Theoretical description
HongGuang Sun, Yong Zhang, Song Wei +1
Non-Newtonian fluid flow might be driven by spatially nonlocal velocity, the dynamics of which can be described by promising fractional derivative models. This short communication…
