Low Mach Asymptotic Preserving Scheme for the Euler-Korteweg Model [PDF]
, 2013 We present an all speed scheme for the Euler-Korteweg model. We study a semi-implicit time-discretisation which treats the terms, which are stiff for low Mach numbers, implicitly and thereby avoids a dependence of the timestep restriction on the Mach ...

Implicit Large-Eddy Simulations of Wall-Bounded Turbulent Flows. [PDF]
, 2007 The paper presents application of Implicit Large Eddy Simulation(ILES)to wall- bounded turbulent flows. A characteristics-based scheme in conjunction with total variation diminishing(TVD)Runge-Kutta time stepping and slope-limiting variants,for the com ...

The spectral discretization of the second-order wave equation
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022 In this paper we deal with the discretization of the second order wave equation by the implicit Euler scheme for the time and the spectral method for the space. We prove that the time semi discrete and the full discrete problems are well posed.

Analysis of the thermoviscoelastic Timoshenko system with diffusion effect
Partial Differential Equations in Applied Mathematics, 2021 This paper is concerned with a new Timoshenko beam model with thermal, mass diffusion and viscoelastic effects. First, by the C0-semigroup theory, we prove the well posedness of the considered problem with Dirichlet boundary conditions.

Convergence of an implicit Euler Galerkin scheme for Poisson–Maxwell–Stefan systems [PDF]
Advances in Computational Mathematics, 2019 A fully discrete Galerkin scheme for a thermodynamically consistent transient Max-well-Stefan system for the mass particle densities, coupled to the Poisson equation for the electric potential, is investigated. The system models the diffusive dynamics of an isothermal ionized fluid mixture with vanishing barycentric velocity.

Semi-Implicit Euler Schemes for Ordinary Differential Inclusions [PDF]
SIAM Journal on Numerical Analysis, 2014 Two semi-implicit Euler schemes for differential inclusions are proposed and analyzed in depth. An error analysis shows that both semi-implicit schemes inherit favorable stability properties from the differential inclusion. Their performance is considerably better than that of the implicit Euler scheme, because instead of implicit inclusions only ...

A bounded upwinding scheme for computing convection-dominated transport problems [PDF]
, 2012 A practical high resolution upwind differencing scheme for the numerical solution of convection-dominated transport problems is presented. The scheme is based on TVD and CBC stability criteria and is implemented in the context of the finite difference ...

Fractional SDEs with stochastic forcing: Existence, uniqueness, and approximation
Nonlinear Analysis, 2023 In this article, we are interested in fractional stochastic differential equations (FSDEs) with stochastic forcing, i.e., to FSDE we add a stochastic forcing term.

Drift-implicit Euler scheme for sandwiched processes driven by Hölder noises
Numerical Algorithms, 2022 AbstractIn this paper, we analyze the drift-implicit (or backward) Euler numerical scheme for a class of stochastic differential equations with unbounded drift driven by an arbitrary λ-Hölder continuous process, λ ∈ (0,1). We prove that, under some mild moment assumptions on the Hölder constant of the noise, the $L^{r}({\Omega };L^{\infty }([0,T]))$
