Numerical approximation of fluid-structure interaction problems [PDF]

Applied and Computational Mechanics, 2008
This paper is devoted to numerical approximations of fluid-structure interaction problems. Namely the problem of interaction of turbulent flow over flexibly supported airfoil is addressed. In order to model the turbulence effects the flow is described by

Approximate Controllability of Second-Grade Fluids [PDF]

Journal of Dynamical and Control Systems, 2020
This paper deals with the controllability of the second grade fluids, a class of non-Newtonian of differentiel type, on a two-dimensional torus. Using the method of Agrachev-Sarychev [1], [2] and of Sirikyan [26], we prove that the system of second grade fluids is approximately controllable by a finite-dimensional control force.

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

Open 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

Fluids, 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

Approximation of Time-Dependent Viscoelastic Fluid Flow: SUPG Approximation [PDF]

SIAM Journal on Numerical Analysis, 2003
Summary: We consider the numerical approximation to the time-dependent viscoelasticity equations with an Oldroyd B constitutive equation. The approximation is stabilized by using a streamline upwind Petrov-Galerkin (SUPG) approximation for the constitutive equation. We analyze both the semidiscrete and fully discrete numerical approximations.

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

AIP 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

International 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]

Royal 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 ...
