Analytical modeling of hyporheic flow for in-stream bedforms: Perturbation method and implementation
Publikováno v:
Environmental Modelling & Software. 111:375-385
Hyporheic flow and nutrient turnover in hyporheic systems are strongly influenced by in-stream bedforms. An accurate representation of topographical variations of the stream-streambed interface is therefore essential in analytical models in order to

A wave equation on a time-dependent domain is considered. The shape of the domain changes according to a prescribed space/time-dependent velocity field. On the moving boundary the solution satisfies zero Dirichlet condition. It is known that if the d

We consider a cantilevered (clamped-free) beam in an axial potential flow. Certain flow velocities may bring about a bounded-response instability in the structure, termed flutter. As a preliminary ...

It is known that the linear Stokes-Lame system can be stabilized by a boundary feedback in the form of a dissipative velocity matching on the common interface [ 5 ]. Here we consider feedback stabilization for a generalized linear fluid-elasticity in

In view of control and stability theory, a recently obtained linearization around a steady state of a fluid-structure interaction is considered. The linearization was performed with respect to an external forcing term and was derived in an earlier pa

A seminal result concerning finite element (FEM) approximations of the Stokes equation was the discrete inf-sup inequality that is uniform with respect to the mesh size parameter. This inequality leads to optimal error estimates for the FEM scheme. T

This study addresses well-posedness of a Mindlin---Timoshenko (MT) plate model that incorporates nonlinear viscous damping and nonlinear source term in Neumann boundary conditions. The main results verify local and global existence of solutions as we

We study the well-posedness of a total linearization, with respect to a perturbation of the external forcing, of a free-boundary nonlinear elasticity--incompressible fluid interaction. The total linearization for the coupling modeled by the Navier--S

The exact controllability problem for several semilinear thin plate models is considered. A distributed control affects a collar of the plate's boundary. The result is semiglobal in the sense that there is no restriction on the size of the initial an

This paper settles a conjecture by Gazzola and Pavani [10] regarding solutions to the fourth order ODE w ( 4 ) + k w ″ + f ( w ) = 0 which arises in models of traveling waves in suspension bridges when k > 0 . Under suitable assumptions on the nonl
