Two-dimensional nanofluid flow impinging on a porous stretching sheet with nonlinear thermal radiation and slip effect at the boundary enclosing energy perspective

open access: yesScientific Reports, 2023
In the current analysis, we examine the heat transmission analysis of nanofluid (NF) movement impinging on a porous extending sheet. The influence of nonlinear thermal radiation (TR), buoyancy force, and slip at the boundary are also examined.

Investigation into the effect of friction decay factor on the modelling and attenuation of stick-slip vibrations of oilwell drilling systems

open access: yesPetroleum, 2022
The self-excited stick-slip oscillations of oilwell drillstrings are attributed to the nonlinear interaction between the drill-bit and the rock formation.

Dynamic analysis of coal stick-slip impact based on physical information neural network

open access: yesMeikuang Anquan, 2023
At present, physical information neural network has become a new paradigm for numerical calculation of engineering mechanics. It can solve partial differential equations by integrating the physical mechanism of neural network in the case of unlabeled ...

Double crystal topographic investigations of PbTe grown by the travelling heater method (THM) [PDF]

open access: yes, 1984
THM-grown PbTe and PbTe: Tl were examined near the (n, - n)-position by means of X-ray double crystal arrangement. The half-width of the rocking curves of Tl doped PbTe is larger than that of undoped PbTe by factor two.

The phase slip factor of the electrostatic cryogenic storage ring CSR

open access: yes, 2017
To determine the momentum spread of an ion beam from the measured revolution frequency distribution, the knowledge of the phase slip factor of the storage ring is necessary. The slip factor was measured for various working points of the cryogenic storage

Approximation of most penetrating particle size for fibrous filters considering Cunningham slip correction factor

open access: yesEnvironmental Engineering Research, 2019
In the estimation of the aerosol single fiber efficiency using fibrous filters, there is a size range, where the particles penetrate most effectively through the fibrous collectors, and corresponding minimum single fiber efficiency.

Determination of critical slip surfaces using mutative scale chaos optimization [PDF]

open access: yes, 2013
Limit equilibrium is a common method used to analyze the stability of a slope, and minimization of the factor of safety or identification of critical slip surfaces is a classical geotechnical problem in the context of limit equilibrium methods for slope ...

The impact of earthquake cycle variability on neotectonic and paleoseismic slip rate estimates [PDF]

open access: yesSolid Earth, 2019
Because of the natural (aleatoric) variability in earthquake recurrence intervals and coseismic displacements on a fault, cumulative slip on a fault does not increase linearly or perfectly step-wise with time; instead, some amount of variability in ...

Grain-orientation induced stress formation in AA2024 monocrystal and bicrystal using Crystal Plasticity Finite Element Method

open access: yesMaterials & Design, 2021
Stress formation of monocrystals and bicrystals is investigated in specific oriented grains and grain boundaries of AA2024 alloy by using Crystal Plasticity Finite Element Method (CPFEM). The simulations show that the maximum Schmid factor (SF) value and
