Hydrogeological structure model of the fault zone in the karst area of north China

open access: yesCarsologica Sinica, 2022
The fault zone has a controlling effect on the mechanical properties and fluid flow characteristics of the crust. It is an extensively distributed and very important structural pattern in the upper crust, and widely participates in the crustal activity ...

Measurements of the Solid-body Rotation of Anisotropic Particles in 3D Turbulence [PDF]

open access: yes, 2014
We introduce a new method to measure Lagrangian vorticity and the rotational dynamics of anisotropic particles in a turbulent fluid flow. We use 3D printing technology to fabricate crosses (two perpendicular rods) and jacks (three mutually perpendicular ...

Geometry aware physics informed neural network surrogate for solving Navier–Stokes equation (GAPINN)

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
Many real world problems involve fluid flow phenomena, typically be described by the Navier–Stokes equations. The Navier–Stokes equations are partial differential equations (PDEs) with highly nonlinear properties. Currently mostly used methods solve this

Assessment of RANS turbulence models and Zwart cavitation model empirical coefficients for the simulation of unsteady cloud cavitation [PDF]

open access: yes, 2019
The numerical simulation of unsteady cavitation flows is sensitive to the selected models and associated parameters. Consequently, three Reynolds Average Navier-Stokes (RANS) turbulence models and the Zwart cavitation model were selected to assess their ...

PyFrac: A planar 3D hydraulic fracture simulator

open access: yes, 2020
Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineered fluid injections. The quantitative prediction of their evolution is critical in order to better understand their dynamics as well as to optimize their
