Semi‐implicit Euler Scheme for Generalized Newtonian Fluids

SIAM Journal on Numerical Analysis, 2006
Rheological behavior of certain non‐Newtonian fluids in engineering sciences is often modeled by power law ansatzes with $p \leq 2$. So far, existing numerical analysis for local strong solutions studies a fully implicit time discretization and find only restricted ranges of admissible p’s for corresponding error estimates [A. Prohl and M.

Impulsive Linearly Implicit Euler Method for the SIR Epidemic Model with Pulse Vaccination Strategy

Axioms
In this paper, a new numerical scheme, which we call the impulsive linearly implicit Euler method, for the SIR epidemic model with pulse vaccination strategy is constructed based on the linearly implicit Euler method. The sufficient conditions for global

Time-Implicit Hydrodynamics for Euler Flows*

ESAIM: Proceedings and Surveys, 2014
We consider the Euler equations with gravity source terms, and derive a time-implicit resolution scheme from the explicit one developed by Vides et al. [8].

Efficient upwind algorithms for solution of the Euler and Navier-stokes equations [PDF]

, 1995
An efficient three-dimensionasl tructured solver for the Euler and Navier-Stokese quations is developed based on a finite volume upwind algorithm using Roe fluxes. Multigrid and optimal smoothing multi-stage time stepping accelerate convergence.

Implicit flux-split schemes for the Euler equations [PDF]

18th Fluid Dynamics and Plasmadynamics and Lasers Conference, 1985
Recent progress in the development of implicit algorithms for the Euler equations using the flux-vector splitting method is described. Comparisons of the relative efficiency of relaxation and spatially-split approximately factored methods on a vector processor for two-dimensional flows are made.

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 ...

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.
