The paperRelaxation Runge-Kutta Methods: Fully-Discrete Explicit Entropy-Stable Schemes for the Compressible Euler and Navier-Stokes Equationsof Mohammed Sayyari, Lisandro Dalcin, Matteo Parsani, David I. Ketcheson, and me has been published inSIAM Journal on Scientific usual, you can find the preprint on arXiv. Abstract: A spectrum of higher-order schemes is developed to solve the Navier-Stokes equations in finite-difference formulations. Pade type formulas of up to sixth order with a five-point stencil are developed for the difference scheme.

A comparative study of two classes of third-order implicit time integration schemes is presented for a third-order hierarchical WENO reconstructed discontinuous Galerkin (rDG) method to solve the 3D unsteady compressible Navier-Stokes equations: 1) the explicit first stage, single diagonally implicit Runge-Kutta (ESDIRK3) scheme, and 2) the Rosenbrock-Wanner (ROW) schemes . Runge Kutta (RK) methods are an important class of methods for integrating initial value problems formed by Kutta methods encompass a wide selection of numerical methods and some commonly used methods such as Explicit or Implicit Euler method, the implicit midpoint rule and the trapezoidal rule are actually simplified versions of a general RK method.

Simulation of 2-D compressible ows on a moving curvilinear mesh with an implicit-explicit Runge-Kutta method Moataz O. Abu AlSaud The purpose of this thesis is to solve unsteady two-dimensional compressible Navier-Stokes equations for a moving mesh using implicit explicit (IMEX) Runge-Kutta scheme. This code computes a steady flow over a bump with the Roe flux by two solution methods: an explicit 2-stage Runge-Kutta scheme and an implicit (defect correction) method with the exact Jacobian for a 1st-order scheme, on irregular triangular grids. A grid generation code is included for a bump problem. - Node-centered finite-volume discretization.

Implicit/explicit (IMEX) Runge-Kutta (RK) schemes are effective for time-marching ODE systems with both stiff and nonstiff terms on the RHS; such schemes implement an (often A-stable or better) implicit RK scheme for the stiff part of the ODE, which is often linear, and, simultaneously, a (more convenient) explicit RK scheme for the nonstiff part of the ODE, which is often Author: CavaglieriDaniele, BewleyThomas.
