Lattice Boltzmann Method Simulations About Shale Gas Diffusion in Sinusoidal Channels

Energy Science &Engineering, EarlyView.
This paper characterizes the microscopic features of shale nanopores using sinusoidal functions and investigates the diffusion effects of methane gas in irregular nanopores through the lattice Boltzmann method. The result shows that methane is significantly influenced by large‐amplitude protrusions of the wall.

Space‐Time Modeling and Numerical Simulations of Non‐Newtonian Fluids Using Internal Variables

International Journal for Numerical Methods in Fluids, EarlyView.
Based on Hamilton's principle, the study focuses on a novel strategy for the modeling of non‐Newtonian fluids with the help of internal variables. Here, the viscosity evolves locally in space and time. Three configurations are numerically implemented, namely channel flow, a benchmark, and a lid‐driven cavity.

Error Analysis of a Pressure‐Correction Method With Explicit Time‐Stepping

International Journal for Numerical Methods in Fluids, EarlyView.
We study explicit variants of this well‐established pressure‐correction scheme for solving the Navier–Stokes equations. Step 3 is replaced by an explicit time‐integration method. We give the complete error analysis for this scheme that allows for highly efficient implementations.
