Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4230-4246, July 2026.ABSTRACT Controlling fracture permeability plays a critical role in subsurface energy applications, particularly in geothermal energy production and enhanced carbon sequestration, where regulating fluid flow is essential. The use of microcapsules has become a promising solution to enhance fracture permeability by providing a controlled sealing ...

Application of Dynamic Smagorinsky Model to the Finite Difference Lattice Boltzmann Method
Journal of Fluid Science and Technology, 2008 Three-dimensional turbulent flows past a square cylinder are simulated by the Finite Difference Lattice Boltzmann Method (FDLBM). We carry out the simulation in two approaches.

A Longitudinal Case Study of a Transnational Teacher's Multiliterate Identity and Pedagogy
Reading Research Quarterly, Volume 61, Issue 3, July/August/September 2026.This study focuses on a teacher's conceptualization of literacy and her literacy pedagogy across her first 4 years living in the United States, as she matriculated into a teacher education program and became a teacher in U.S. schools. Data included a digital story she composed as a preservice teacher, additional coursework artifacts, and interviews ...

An approximate inertial manifold (AIM) based closure for turbulent flows
AIP Advances, 2022 A closure model for turbulent flows is developed based on a dynamical system theory. An appropriately discretized formulation of the governing equations is considered for this process.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract In Earth system models, three‐dimensional prognostic subsurface hydrodynamics, including groundwater flow, are currently missing at the global scale. In order to prepare Earth system models for kilometer‐scale simulations with integrated continental hydrology, the ParFlow hydrological model has been coupled to the land model of the ICON ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract Numerical experimentation using an atmospheric configuration of the Goddard Earth Observing System (GEOS) Earth System Model is used to examine the vertical structure of the simulated Quasi‐Biennial Oscillation (QBO). Using an improved representation of the parameterized gravity wave spectrum, it is demonstrated that with sufficient vertical ...
