Аннотация: We consider a combination of semi-Lagrangian approach and finite element method for initial boundary-value problem for the Navier-Stokes equations. To construct a numerical method, we use uniform space mesh and trilinear functions. For system of Navier-Stokes equations we apply splitting method. We use conservative semi-Lagrangian Показать полностьюapproach for continuity equation. We write momentum equations and equation for internal energy with help of Lagrangian derivative. According to finite element method, we consider weak formulation and get integral equations. To define numerical solution, we approximate integral of Lagrangian derivative according to semi-Lagrangian approach. Other integrals we compute with help of quadrature formulas. © 2020 American Institute of Physics Inc.. All rights reserved.
