Under the Mori–Tanaka micro-mechanics scheme, the effective non-linear behaviour is predicted for various micro-parameters such as the aspect ratio and mass fractions.
In process of fitting the macro-parameters, the related micro-parameters such as pore structure parameters and surface properties parameters are adjusted properly to establish the network model.
There is some internal relationship between the variation of reservoir macro-parameters (such as porosity, permeability, and relative permeability curve) and the variation of micro-parameters (such as pore radius, aspect ratio, shape factor, and coordination number).
The variation of the plastic properties can subsequently be related to important micro-structural parameters such as particle composition, dislocation density and grain size.
From acoustical measurements, simple analytical equations allow to estimate key micro-structural parameters such as tortuosity, viscous and thermal characteristic lengths and resistivity.
Mercury intrusion porosimetry (MIP) is used to experimentally determine micro-structural parameters such as porosity, tortuosity and effective diffusion coefficients, which are used in the diffusion equations for the porous anode layer.
In the literature, the effective macro-scale diffusion coefficients are now well established, while uncertainty remains concerning the relationship between the effective thermodiffusion coefficient and micro-scale parameters (such as pore-scale geometry).
The efficacy of the proposed study is illustrated by investigating the effective response for several network realizations, incorporating the influence of different micro-scale parameters, such as fibre hygro-thermo-elastic properties, orientation, geometry, areal coverage.
The morphology evolution of TLCP in the hybrid blends, especially at 7 wt% of clay loading, was consistent well with the prediction based on the micro-rheology parameters such as the viscosity ratio of the dispersed phase to the matrix (ηd/ηm) and the ratio of capillary number to the critical capillary number (Ca/Cacrit).
The verified model was then employed to conduct a parametric study considering important micro-tunneling design parameters, such as depth and diameter of the tunnel, in situ stress ratio (Ko), and the time lapse prior to replacing LFs with permanent cement grout around the tunnel.
