Near-wall effects in rarefied gas micro-flows: some modern hydrodynamic approaches

, 2005
Methods for simulating the critical near-wall region in hydrodynamic models of gas micro-flows are discussed. Two important non-equilibrium flow features - velocity slip at solid walls, and the Knudsen layer (which extends one or two molecular mean free ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Hydrodynamic and Acoustic Performance Analysis of Marine Propellers by Combination of Panel Method and FW-H Equations

Mathematical and Computational Applications, 2019
The noise emitted by ships is one of the most important noises in the ocean, and the propeller noise is one of the major components of the ship noise. Measuring the propeller noise in a laboratory, despite the high accuracy and good reliability, has high

Effect of channel geometry on a density wave induced by gravity and chemoconvection in miscible reacting fluids

AIP Advances, 2020
We study a two-layer system of initially separated aqueous solutions of an acid and a base placed in a vertically oriented Hele–Shaw cell. After the reactants, a second-order neutralization reaction begins, which is accompanied by the release of salt ...
