Universal discontinuous percolation transition in the Earth's terrestrial topography
Shengjie Hu, Zhenlei Yang, Zipeng Wang +2
Based on the Topographic Wetness Index (TWI), we studied the percolation process of water on the Earth's land surface and discovered a universal discontinuous phase transition acro…
Converging trend of global urban land expansion sheds new light on sustainable development
Shengjie Hu, Zhenlei Yang, Sergio Andres Galindo Torres +5
Urban land growth presents a major sustainability challenge, yet its growth patterns and dynamics remain unclear. We quantified urban land evolution by analyzing its statistical di…
Random-Walk Metaball-Imaging Discrete Element Lattice Boltzmann Method for 3D Solute Transport in Fluid-Particle Systems with Complex Granular Morphologies
Yifeng Zhao, Pei Zhang, Stan Z. Li +1
Solute transport in fluid-particle systems is a fundamental process in numerous scientific and engineering disciplines. The simulation of it necessitates the consideration of solid…
Shear viscosity scaling of granular suspensions across dilute to dense regimes
Zaohui Zhang, Teng Man, Herbert E. Huppert +1
In this letter, following an extensive experimental validation, we perform constant-volume shearing simulations of non-Brownian granular suspensions using the discrete element meth…
Mean Stress Tensor of Discrete Particle Systems in Submerged Conditions
Zhuan Ge, Teng Man, Sergio Andres Galindo-Torres
The mean stress tensor is essential to investigate the dynamics of granular material. In this paper, we use Hamilton's principle of least action to derive the averaged stress tenso…
A Data-driven feature selection and machine-learning model benchmark for the prediction of longitudinal dispersion coefficient
Yifeng Zhao, Pei Zhang, S. A. Galindo-Torres +1
Longitudinal Dispersion(LD) is the dominant process of scalar transport in natural streams. An accurate prediction on LD coefficient(Dl) can produce a performance leap in related s…
