Surface Roughness and Hydrodynamic Boundary Conditions [PDF]

Physical Review E, 2006
We report results of investigations of a high-speed drainage of thin aqueous films squeezed between randomly nanorough surfaces. A significant decrease in hydrodynamic resistance force as compared with predicted by Taylor's equation is observed. However,

Hydrodynamic Kelvin–Helmholtz instability on metallic surface

Scientific Reports, 2023
Kelvin–Helmholtz instability on metallic surface is relevant to intense oblique impact in many physical processes such as explosive welding, Inertial Confinement Fusion and planetary impact events.

The Surface Layers Dual to Hydrodynamic Boundaries [PDF]

Nuclear Physics B, 2010
The AdS/hydrodynamics correspondence provides a 1-1 map between large wavelength features of AdS black branes and conformal fluid flows. In this note we consider boundaries between nonrelativistic flows, applying the usual boundary conditions for viscous

Irreversible hydrodynamic trapping by surface rollers [PDF]

Soft Matter, 2020
A microscopic colloidal roller propelling along a flat rigid surface can irreversibly trap and transport passive cargo through cross-streamline migration induced by steric interaction between the cargo and the interface.

Hydrodynamics of Sperm Cells near Surfaces [PDF]

Biophysical Journal, 2010
Sperm are propelled by an actively beating tail, and display a wide variety of swimming patterns. When confined between two parallel walls, sperm swim either in circles or on curvilinear trajectories close to the walls. We employ mesoscale hydrodynamics simulations in combination with a mechanical sperm model to study the swimming behavior near walls ...

Hydrodynamic Attraction of Swimming Microorganisms by Surfaces [PDF]

Physical Review Letters, 2008
Cells swimming in confined environments are attracted by surfaces. We measure the steady-state distribution of smooth-swimming bacteria (Escherichia coli) between two glass plates. In agreement with earlier studies, we find a strong increase of the cell concentration at the boundaries.

Determination of the Hydrodynamic Characteristics of a Typical Inland Saline-Alkali Wetland in Northeast China

Frontiers in Ecology and Evolution, 2022
Hydrological connectivity in wetland ecosystems comprises a combination of hydrodynamic, hydrochemical, and biological characteristics. Hydrodynamic characteristics are important for the transmission of energy, matter, and information between surface ...

Surface Roughness and Effective Stick-Slip Motion [PDF]

, 2002
The effect of random surface roughness on hydrodynamics of viscous incompressible liquid is discussed. Roughness-driven contributions to hydrodynamic flows, energy dissipation, and friction force are calculated in a wide range of parameters.

Regulation of vegetation pattern on the hydrodynamic processes of erosion on hillslope in Loess Plateau, China

Journal of Groundwater Science and Engineering, 2023
As vegetation are closely related to soil erosion, hydrodynamic parameter changes under various vegetation pattern conditions can be used as an important basis for the research of the soil erosion mechanism.

Determination of hydrodynamic forces acting on the body in an unsteady viscous flow using characteristics of the flow on the control surface

Учёные записки Казанского университета: Серия Физико-математические науки, 2022
This article considers the problem of determining the hydrodynamic forces acting on the body in an unsteady flow on a distant control surface. General formulas for calculating hydrodynamic forces in the three- and two-dimensional cases were derived.
