Numerical Investigations of Slip Effects on Rarefied Gas Flows by First and Second-Order Slip Boundaries

open access: yesJournal of Fluid Science and Technology, 2012
This paper discusses comparisons of first and second-order slip boundary conditions on the range of Knudsen numbers of some typical MEMS as O(10-3)<Kn<O(10-1) by numerical simulations using the continuum model based on the Navier-Stokes (N-S ...

Compression at Strike‐Slip Fault Is a Favorable Condition for Subduction Initiation

open access: yesGeophysical Research Letters, 2023
The recent statistics suggests that over 60% of active Cenozoic subduction initiation (SI) cases are related to the strike‐slip fault. A number of previous studies have shown that the lithospheric weak zone is a necessary condition for the SI.

Transient Flow Through a Porous Channel with Ramped Pressure Gradient and Velocity Slip Boundary Condition

open access: yesInternational Journal of Applied Mechanics and Engineering, 2022
A transient flow formation of an incompressible fluid through a horizontal porous channel assuming a ramped pressure gradient is considered with the velocity slip boundary conditions.

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

An apparent oil permeability model for shale oil reservoir with mixed-wet nanopores

open access: yesYouqi dizhi yu caishoulu
Shale oil reservoir is a typical unconventional oil and gas resource that plays an essential role in the international energy supply market. Due to the complex pore structure and crude oil composition of shale oil reservoirs, the flow of crude oil in ...

Simulation of Micro-Channel and Micro-Orifice Flow Using Lattice Boltzmann Method with Langmuir Slip Model [PDF]

open access: yesTransport Phenomena in Nano and Micro Scales, 2016
Because of its kinetic nature and computational advantages, the Lattice Boltzmann method (LBM) has been well accepted as a useful tool to simulate micro-scale flows.

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

open access: yesAdvanced 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.

Fullerene-water nanofluid confined in graphene nanochannel

open access: yesAIP Advances, 2017
The flow behaviors and boundary slip of the fullerene-water nanofluids (NFs) confined in graphene nanochannels are first investigated by using classical molecular dynamics simulations.
