#### An elementary nonlinear beam theory with finite buckling deformation properties

(Siam Publications, 2002-04)

A simple nonlinear beam model is derived from basic principles. The assumption upon which the derivation is based is that axial motions are of second order compared with transverse motions of the beam. The existence of ...

#### Model reduction of descriptor systems by interpolatory projection methods

(Siam Publications, 2013)

In this paper, we investigate an interpolatory projection framework for model reduction of descriptor systems. With a simple numerical example, we first illustrate that directly applying the subspace conditions from the ...

#### a numerical study of periodic disturbances on two-layer Couette flaw

(AIP Publishing, 1998-12)

The flow of two viscous liquids is investigated numerically with a volume of fluid scheme. The scheme incorporates a semi-implicit Stokes solver to enable computations at low Reynolds numbers, and a second-order velocity ...

#### Couette flow of a binary gas mixture

(AIP Publishing, 1988-03)

The linearized binary model described by Hamel [Phys. Fluids 8, 418 (1964)] is used to obtain a set of kinetic equations and boundary conditions for the Couette flow problem. The derived set of two coupled integrodifferential ...

#### Preconditioning Parametrized Linear Systems

Preconditioners are generally essential for fast convergence in the iterative solution of linear systems of equations. However, the computation of a good preconditioner can be expensive. So, while solving a sequence of ...

#### Deformation of a hydrophobic ferrofluid droplet suspended in a viscous medium under uniform magnetic fields

(Cambridge University Press, 2010-11)

The effect of applied magnetic fields on the deformation of a biocompatible hydrophobic ferrofluid drop suspended in a viscous medium is investigated numerically and compared with experimental data. A numerical formulation ...

#### Numerical Approximations of the Dynamical System Generated by Burgers' Equation with Neumann-Dirichlet Boundary Conditions

(EDP Sciences, 2013-09)

Using Burgers' equation with mixed Neumann-Dirichlet boundary conditions, we highlight a problem that can arise in the numerical approximation of nonlinear dynamical systems on computers with a finite precision floating ...

#### Effect of inertia on drop breakup under shear

(American Institute of Physics, 2001-01)

A spherical drop, placed in a second liquid of the same density and viscosity, is subjected to shear between parallel walls. The subsequent flow is investigated numerically with a volume-of-fluid continuous-surface-force ...

#### Radial oscillations of encapsulated microbubbles in viscoelastic liquids

(American Institute of Physics, 2002-10)

The small-amplitude radial oscillations of a gas microbubble encapsulated by a viscoelastic solid shell and surrounded by a slightly compressible viscoelastic liquid are studied theoretically. The Kelvin-Voigt and 4-constant ...

#### Sound-ultrasound interaction in bubbly fluids: Theory and possible applications

(American Institute of Physics, 2001-12)

The interaction between sound and ultrasound waves in a weakly compressible viscous liquid with gas bubbles is considered. Using the method of multiple scales one- and two-dimensional nonlinear interaction equations are ...
