TL;DR: In this article, a unique model was proposed to describe the spatial and temporal distribution of coal permeability within the effective influence zone, and a parametric study on both two models was also conducted, in which the effect of extraction time, extraction pressure, interval between two boreholes, and extraction pressure combination were qualitatively analyzed.

TL;DR: In this paper, the authors present a review of the state-of-the-art in the design of biomass handling and feeding equipment using both experiments and numerical modeling, which leverage both numerical and experimental data.

TL;DR: In this article, a numerical method is proposed to simulate multi-scale fracture propagation driven by fluid injection in transversely isotropic porous media, which can account for material and stress anisotropy at the continuum scale, by using a damage model in which two equivalent strains are defined to distinguish mechanical behavior in the direction parallel and perpendicular to the layer.

TL;DR: The discrete damage model presented in this paper accounts for 42 non-interacting crack microplanes directions at the scale of the representative volume element, the free enthalpy is the sum of th...

TL;DR: In this paper, the authors present the theoretical formulation and numerical implementation of an anisotropic damage model for materials with intrinsic transverse isotropy, which is modeled by phenomenological damage evolution laws, controlled by four equivalent strain measures.
