Beyond the no-slip boundary condition [PDF]

Physical Review E, 2011
This paper offers a simple macroscopic approach to the question of the slip boundary condition to be imposed upon the tangential component of the fluid velocity at a solid boundary. Plausible reasons are advanced for believing that it is the energy equation rather than the momentum equation that determines the correct fluid-mechanical boundary ...

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.

Influence of slip boundary on flow separation and drag of flow past bluff body at high Reynolds numbers

Zhongguo Jianchuan Yanjiu, 2022
ObjectivesFlow separation increases the drag and noise of underwater vehicles, and influences the controllability of their control surfaces. Therefore, the influence of slip caused by superhydrophobic surfaces on drag reduction and flow separation is ...

Study of the Effect of Grain-Boundary Misorientation on Slip Transfer in Magnesium Alloy Using a Misorientation Distribution Map

Crystals, 2022
The microstructure evolution of a Mg–Gd–Y alloy was studied using uniaxial tension combined with an electron backscatter diffraction technique. The results show that large amounts of slip transfer phenomena can be observed around the grain–boundary area ...

A Liouville theorem for the planer Navier-Stokes equations with the no-slip boundary condition and its application to a geometric regularity criterion [PDF]

, 2013
We establish a Liouville type result for a backward global solution to the Navier-Stokes equations in the half plane with the no-slip boundary condition. No assumptions on spatial decay for the vorticity nor the velocity field are imposed.

Dual solutions of slip flow past a nonlinearly shrinking permeable sheet

Alexandria Engineering Journal, 2016
The aim of the paper is to investigate the flow of an incompressible viscous fluid past a nonlinearly shrinking permeable sheet. Partial slip condition is considered instead of no slip condition at the boundary.

The role of incoherent twin boundaries on the plasticity of Cu micropillars

Materials & Design, 2023
The role of a ∑3{112} incoherent twin boundary (ITB) on the shear stress of Cu at the micron scale has been investigated through microcompression of bi-crystalline pillars containing ITB, as well as single-crystalline pillars, in two different ...

Viscous heating and cooling process in a mixed convection cavity with free-slip effect

Case Studies in Thermal Engineering, 2021
Both no-slip and free-slip effects are enforced to the lid-driven cavity walls with Robin boundary condition. Viscous heating and cooling process happen when the shear force applied at the top lid is removed and the cavity is exposed to natural ...

Quantifying effective slip length over micropatterned hydrophobic surfaces [PDF]

, 2009
We employ micro-particle image velocimetry ($\mu$-PIV) to investigate laminar micro-flows in hydrophobic microstructured channels, in particular the slip length.

Solution of Time Periodic Electroosmosis Flow with Slip Boundary

Abstract and Applied Analysis, 2014
Recent research confirms that slip of a fluid on the solid surface occurs at micrometer scale. Slip on solid surface may cause the change of interior material deformation which consequently leads to the change of velocity profile and stress field.
