Experimental investigation of hydrodynamics of melt layer during laser cutting of steel [PDF]

open access: yes, 2011
In laser cutting process, understanding of hydrodynamics of melt layer is significant, because it is an important factor which controls the final quality. In this work, we observed hydrodynamics of melt layer on kerf front in the case of laser cutting of

Numerical investigation of nonlinear wave passing through finite circular array of slender cylinders

open access: yesEngineering Applications of Computational Fluid Mechanics, 2019
Cylinders extend from the plat bottom of an open channel piercing the water free surface to mimic a patch of emergent vegetation and are often used as models in numerical simulations or experiments related to flow in the presence of vegetation. This work

Comparative hydrodynamic and nanoscale imaging study on the interactions of teicoplanin-A2 and bovine submaxillary mucin as a model ocular mucin

open access: yesScientific Reports, 2023
Glycopeptide antibiotics are regularly used in ophthalmology to treat infections of Gram-positive bacteria. Aggregative interactions of antibiotics with mucins however can lead to long exposure and increases the risk of resistant species.

Tomographic study of the structure of cast and pressed trotyl charges

open access: yesResults in Engineering, 2022
The sensitivity of condensed explosives depends strongly on the charge structure. Trotyl (TNT) is a typical example of such dependence. The pressed charges are more sensitive than the cast ones, which was confirmed in many studies including critical ...

Evaluation and accuracy of the local velocity data measurements in an agitated vessel

open access: yesEPJ Web of Conferences, 2014
Velocity measurements of the flow field in an agitated vessel are necessary for the improvement and better understanding of the mixing processes. The obtained results are used for the calculations of the impeller pumping capacity, comparison of the power

Structure of turbulent velocity field in the discharge stream from a standard Rushton turbine impeller [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2017
The radial discharge jet from a standard Rushton turbine was investigated by the Laser Doppler Anemometry (LDA) method. Several distances from the impeller blades (in the radial direction) were chosen for the measurement of axial profiles: all three ...

Research progress and application of computational method for hydrodynamic noise from air-water interface

open access: yesZhongguo Jianchuan Yanjiu, 2022
Hydrodynamic noise from an air-water interface is often encountered in marine engineering structures. It involves a complex mechanism, various forms of sound sources and many factors affecting the propagation.

Durability of a Drag Reducing Solution

open access: yesApplied Rheology, 2008
Effectiveness of drag reduction by small addition of a surfactant in the turbulent flow of water depends on the structure and concentration of the additive, temperature of the solution and turbulence intensity, possible flow disturbance by a mechanical ...

Using stability analysis of discrete elastic systems to study the buckling of nanostructures

open access: yesArchives of Mechanics, 2012
Stubility/instability criteria of discrete elastic systems are used to study the buckling of nanostructures. The deformation of nanostructures is simulated by solving the nonlinear equations of molecular mechanics.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
