Multilayer approximation for a confined fluid in a slit pore [PDF]

open access: yesPapers in Physics, 2010
A simple Lennard-Jones fluid confined in a slit nanopore with hard walls is studied on the basis of a multilayer structured model. Each layer is homogeneous and parallel to the walls of the pore.

Electroosmotic flow for Eyring fluid with Navier slip boundary condition under high zeta potential in a parallel microchannel

open access: yesOpen Physics, 2022
The electroosmotic flow of non-Newtonian fluid–Eyring fluid in microparallel pipes under high zeta potential driven by the combination of pressure and electric force is studied.

Calculation of Thermodynamic Characteristics and Sound Velocity for Two-Dimensional Yukawa Fluids Based on a Two-Step Approximation for the Radial Distribution Function

open access: yesFluids, 2023
We propose a simple two-step approximation for the radial distribution function of a one-component two-dimensional Yukawa fluid. This approximation is specified by the key parameters of the system: coupling parameter and screening parameter. On the basis

Approximate solution to a generalized Van der Pol equation arising in plasma oscillations

open access: yesAIP Advances, 2022
Motivated by some published theoretical investigations and based on the two-fluid model, nonlinear plasma oscillations are analyzed and discussed in the framework of the generalized Van der Pol equation.

Analysis of the Dynamics of a Freely Falling Body in a Viscous Fluid: Computational Fluid Dynamics Approach

open access: yesInternational Journal of Thermofluids, 2022
The dynamics of solid objects falling through a viscous fluid was studied. The forces that control the motion as well as the effects of fluid viscosity and object density were studied using an analytical model.

An approximate solution for a penny-shaped hydraulic fracture that accounts for fracture toughness, fluid viscosity and leak-off [PDF]

open access: yesRoyal Society Open Science, 2016
This paper develops a closed-form approximate solution for a penny-shaped hydraulic fracture whose behaviour is determined by an interplay of three competing physical processes that are associated with fluid viscosity, fracture toughness and fluid leak ...

Two Types of Waves in a Two-Layer Stratified Fluid

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2023
Within the framework of the linear theory of small potential oscillations the article studies the structure and characteristics of internal and surface waves in a two-layer stably stratified fluid.

Unsteady Dean flow formation in an annulus with partial slippage: A riemann-sum approximation approach

open access: yesResults in Engineering, 2020
This paper investigates time-dependent Dean Flow of an incompressible fluid under homogeneous slip, non-homogeneous slip, and no-slip boundary conditions. The fluid flow is due to the sudden application of an azimuthal pressure gradient.

Approximation models for the evaluation of TCP/AQM networks [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2022
The article proposes a model in which Diffusion Approximation is used to analyse the TCP/AQM transmission mechanism in a multinode computer network. In order to prevent traffic congestion, routers implement AQM (Active Queue Management) algorithms.

The Stationary Behaviour of Fluid Limits of Reversible Processes is Concentrated on Stationary Points [PDF]

open access: yes, 2012
Assume that a stochastic processes can be approximated, when some scale parameter gets large, by a fluid limit (also called "mean field limit", or "hydrodynamic limit").
