Steady Stokes flow of a non-Newtonian Reiner-Rivlin fluid streaming over an approximate liquid spheroid

open access: yesApplied and Computational Mechanics, 2020
The investigation is carried out to study steady Stokes axisymmetrical Reiner-Rivlin streaming flow over a fixed viscous droplet, and this droplet to be deformed sphere in shape.

Viscous-Inviscid Interactions in a Boundary-Layer Flow Induced by a Vortex Array

open access: yes, 2014
In this paper we investigate the asymptotic validity of boundary layer theory. For a flow induced by a periodic row of point-vortices, we compare Prandtl's solution to Navier-Stokes solutions at different $Re$ numbers.

Slow oscillatory Stokes flow [PDF]

open access: yesQuarterly of Applied Mathematics, 1997
Two transient problems in slow viscous flow are considered where the corresponding steady-state behaviour leads to the paradoxical results of Stokes and Jeffery. First, the oscillatory flow past a circular cylinder is investigated when the frequency λ \lambda tends to zero, where an outer domain of size O

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

open access: yesAdvanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential

Solutions of Navier-Stokes Equation with Coriolis Force

open access: yesAdvances in Mathematical Physics, 2017
We investigate the Navier-Stokes equation in the presence of Coriolis force in this article. First, the vortex equation with the Coriolis effect is discussed.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Influence of the wall roughness on a linear shear flow [PDF]

open access: yesFME Transactions, 2018
In this paper, we will be interested in the viscous flow fluid over a rough wall which has a periodic roughness and small amplitude. The Reynolds number for the flow over a rough wall is low and the creeping flow equations apply.

A Review of Critical Conditions for the Onset of Nonlinear Fluid Flow in Rock Fractures

open access: yesGeofluids, 2017
Selecting appropriate governing equations for fluid flow in fractured rock masses is of special importance for estimating the permeability of rock fracture networks.

Well-posedness analysis of a stationary Navier–Stokes hemivariational inequality

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2021
This paper provides a well-posedness analysis for a hemivariational inequality of the stationary Navier-Stokes equations by arguments of convex minimization and the Banach fixed point.

On the Stokes number and characterization of aerosol deposition in the respiratory airways [PDF]

open access: yes, 2015
Aerosol deposition in the respiratory airways has traditionally been examined in terms of the Stokes number based on the reference flow timescale. This choice leads to large scatter in deposition efficiency when plotted against the reference Stokes ...
