On Some Numerical Dissipation Schemes [PDF]
Journal of Computational Physics, 1998 We consider several schemes for introducing an artificial dissipation into a central difference approximation to Euler and Navier-Stokes equations. The focus is on the convective upwind split pressure scheme, which is designed to support single interior point discrete shock waves.

Axioms, 2023 In this article, we present a numerical iterative scheme for solving a non-local singular initial-boundary value problem by combining two well known efficient methods. Namely, the homotopy analysis method and the double Laplace transform method.

Mathematics, 2021 In this article, we propose a novel mathematical model for the spread of COVID-19 involving environmental white noise. The new stochastic model was studied for the existence and persistence of the disease, as well as the extinction of the disease.

Comparative analysis of different numerical schemes in solute trapping simulations by using the phase-field model with finite interface dissipation [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2016 Two different numerical schemes, the standard explicit scheme and the time-elimination relaxation one, in the framework of phase-field model with finite interface dissipation were employed to investigate the solute trapping effect in a Si-4.5 at.

Modeling and analysis of the addiction of social media through fractional calculus
Frontiers in Applied Mathematics and Statistics, 2023 Social media addiction (SMA) is the excessive use of social media platforms, resulting in negative consequences for individuals. It is characterized by an uncontrollable urge to use social media, leading to negative effects in human's life.

Stable schemes for second-moment turbulent models for incompressible flows
Comptes Rendus. Mécanique, 2023 A stable scheme is proposed in this paper in order to obtain approximate solutions of second-moment turbulent models for incompressible flows with or without thermal transport equation. The analysis of the convective terms, which includes the solution of

A Rapid Solver for the Prediction of Flow-Field of High-Speed Vehicle Moving in a Tube
Energies, 2022 High-speed vehicles traveling in a tube with pressures similar to those experienced by aircraft at their maximum altitude are presented. Although the concept resembles Hyperloop, the pressure level investigated here is much higher and safer than that ...

Symmetry-Preserving Numerical Schemes [PDF]
, 2017 In these lectures we review two procedures for constructing finite difference numerical schemes that preserve symmetries of differential equations. The first approach is based on Lie's infinitesimal symmetry generators, while the second method uses the novel theory of equivariant moving frames.

Numerical schemes for nonlinear predictor feedback [PDF]
Mathematics of Control, Signals, and Systems, 2014 Implementation is a common problem with feedback laws with distributed delays. This paper focuses on a specific aspect of the implementation problem for predictor-based feedback laws: the problem of the approximation of the predictor mapping. It is shown that the numerical approximation of the predictor mapping by means of a numerical scheme in ...
