Determination of basic parameters of unimodal and bimodal soil water characteristic curves

Yantu gongcheng xuebao, 2017
The determination of basic parameters (such as air-entry value, residual suction, slope at transition zone, etc.) of soil-water characteristic curve (SWCC) is the most fundamental for predicting the strength, permeability and constitutive relation of ...

Pore Structure of Grain-Size Fractal Granular Material [PDF]

, 2019
Numerous studies have proven that natural particle-packed granular materials, such as soil and rock, are consistent with the grain-size fractal rule. The majority of existing studies have regarded these materials as ideal fractal structures, while few ...

Soil Water Retention: Uni-Modal Models of Pore-Size Distribution Neglect Impacts of Soil Management [PDF]

, 2018
Most models describing soil water retention imply a uni-modal pore-size distribution (PSD). The uni-modal model presented by van Genuchten (termed vanG) is widely used although double-exponential models (termed Dex) implying a bi-modal PSD may better ...

Do Pores Exist?—Foundational Issues in Pore Structural Characterisation

Foundations
This work reviews a range of fundamental theoretical considerations in pore structural characterisation. The pore concept is essential for providing a better understanding of physical processes arising within porous media than purely phenomenological ...

Pore Strategy Design of a Novel NiTi-Nb Biomedical Porous Scaffold Based on a Triply Periodic Minimal Surface

Frontiers in Bioengineering and Biotechnology, 2022
The pore strategy is one of the important factors affecting the biomedical porous scaffold at the same porosity. In this work, porous scaffolds were designed based on the triply periodic minimal surface (TPMS) structure under the same porosity and ...
