Effect of Submerged Vegetation on Water Surface Geometry and Air–Water Momentum Transfer
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Understanding how submerged vegetation modifies the water surface is crucial for modeling momentum exchange between shallow waters and the atmosphere. In particular, quantifying its impact on the equivalent aerodynamic roughness of the water surface is essential for improved boundary‐layer parameterization in oceanic and atmospheric models. In

Chemical Engineering Science, 2019 Two-phase flow in three porous media with different geometry complexities are simulated using the Volume-of-Fluid (VOF) method. The evolution of the flow pattern, as well as the dynamics involved are simulated and compared to experiments. For a simple geometry and smooth solid surface, like single capillary rise experiment, VOF simulation gives results

Wide‐Flow Aerosol Jet Printing Enables High‐Throughput, Ultra‐Low Aspect Ratio Patterning
Advanced Science, Volume 13, Issue 3, 14 January 2026.Wide‐flow aerosol jet printing (WF‐AJP) employs an anisotropic nozzle design to generate planar aerosol jets, enabling millimeter‐scale deposition of highly uniform, ultra‐low aspect ratio (<1:6000) films with substantially reduced anisotropy in functional performance.

3D avalanche flow modeling using OpenFOAM
Труды Института системного программирования РАН, 2018 In this paper, a model of a snow avalanche was created with the help of open source CFD software OpenFOAM. The avalanche is considered as a turbulent two-phase flow - snow and air. We take incompressible Herschel-Balkley fluid as a model of snow.

Effects of Triangular Nozzle Geometry on the Deformation and Breakup of Liquid Jets in Crossflow
Chemical Engineering &Technology, Volume 49, Issue 1, January 2026.This study numerically investigates the deformation and breakup of liquid jets in air crossflow from triangular and circular nozzles using Newtonian and shear‐thinning fluids. The analysis highlights how non‐circular geometry and rheology jointly govern jet instability through variations in viscosity, pressure, and energy transfer. The findings advance

International Journal of Naval Architecture and Ocean Engineering, 2009 In this paper we validate a numerical model for wave-structure interaction by comparing numerical results with laboratory data. The numerical model is based on the Navier-Stokes (N-S) equations for an incompressible fluid. The N-S equations are solved by
