A Viscous Fluid Flow through a Thin Channel with Mixed Rigid-Elastic Boundary: Variational and Asymptotic Analysis

Abstract and Applied Analysis, 2012
We study the nonsteady Stokes flow in a thin tube structure composed by two thin rectangles with lateral elastic boundaries which are connected by a domain with rigid boundaries.

Fourier Truncation Regularization Method for a Time-Fractional Backward Diffusion Problem with a Nonlinear Source

Mathematics, 2019
In present paper, we deal with a backward diffusion problem for a time-fractional diffusion problem with a nonlinear source in a strip domain. We all know this nonlinear problem is severely ill-posed, i.e., the solution does not depend continuously on ...

hp-FEM for the $$\alpha $$-Mosolov problem: a priori and a posteriori error estimates

Numerische Mathematik
AbstractAn hp-finite element discretization for the $$\alpha $$ α -Mosolov problem, a scalar variant of the Bingham flow problem but with the $$\alpha $$ α -Laplacian operator, is being analyzed.

A priori error estimates for the $θ$-method for the flow of nonsmooth velocity fields

CoRR
Velocity fields with low regularity (below the Lipschitz threshold) naturally arise in many models from mathematical physics, such as the inhomogeneous incompressible Navier-Stokes equations, and play a fundamental role in the analysis of nonlinear PDEs.

A posteriori and a priori error estimates for linearized thin sheet folding

We describe \emph{a posteriori} error analysis for a discontinuous Galerkinmethod for a fourth-order elliptic interface problemarising from a linearized model of thin sheet folding.The primary contribution is a local efficiency bound for an estimator that measuresthe extent to which the interface conditions along the fold are satisfied,obtained via a ...

The Penalty resolution of the spectral element discretization of the time dependent Darcy equations

Boundary Value Problems
The time-dependent Darcy system, when discretized in time using the implicit Euler scheme and in space using the spectral element method, can be efficiently solved using the penalty method.

A wavelet method for solving backward heat conduction problems

Electronic Journal of Differential Equations, 2017
In this article, we consider the backward heat conduction problem (BHCP). This classical problem is more severely ill-posed than some other problems, since the error of the data will be exponentially amplified at high frequency components.
