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 ...

On numerical approximations to fluid–structure interactions involving compressible fluids

open access: yesNumerische Mathematik, 2022
In this paper we introduce a numerical scheme for fluid-structure interaction problems in two or three space dimensions: A flexible elastic plate is interacting with a viscous, compressible barotropic fluid. Hence the physical domain of definition (the domain of Eulerian coordinates) is changing in time.

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.

Fluid Approximation of Pool Depletion Systems [PDF]

open access: yes, 2016
Today’s most of high performance computing applications use parallel programming paradigms to reach the desired efficiency objectives. In particular, they divide the problem into small elements that can be solved in parallel by as many computing devices as available. Some examples are Apache Spark, the evolution of Hadoop and map-reduce, GPGPU (General

State Equations in Stochastic Process Algebra Models

open access: yesIEEE Access, 2019
State equations are usually used for structural or qualitative analysis, such as deadlock checking, in P/T systems. In this paper, we instead consider timed state equations in stochastic process algebra models, to derive quantified dynamic information on

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.

Don't Just Go with the Flow: Cautionary Tales of Fluid Flow Approximation [PDF]

open access: yes, 2012
Fluid flow approximation allows efficient analysis of large scale PEPA models. Given a model, this method outputs how the mean, variance, and any other moment of the model’s stochastic behaviour evolves as a function of time.
