We re-visit the semi-Lagrangian Runge–Kutta exponential integrators presented in Celledoni et al. (J Sci Comput 41:139–164, 2009) for Convection-dominated convection-diffusion problems. Third order accurate methods of this class consist of subset

A generalized cubic equation of state is given. The Peng-Robinson and the Soave-Redlich-Kwong equations are special cases of this equation. The generalized equation of state is precisely as simple and computationally efficient as these classical equa

Large-scale models of carbon dioxide (CO2) storage in geological formations must capture the relevant physical, chemical and thermodynamic processes that affect the migration and ultimate fate of injected CO2. These processes should be modeled over t

Implicit-explicit (IMEX) multistep methods are very useful for the time discretization of convection diffusion PDE problems such as the Burgers equations and the incompressible Navier-Stokes equations. In the latter as well as in PDE models of plasma

In this paper we consider the case of nonlinear convection-diffusion problems with a dominating convection term and we propose exponential integrators based on the composition of exact pure convection flows. These methods can be applied to the numeri

Relationships between pressure, temperature and density are generally described by an equation of state. For CO2, the Span-Wagner equation is generally assumed to give the best fit to measured data. The high accuracy of this equation does not come wi

We propose a class of semi-Lagrangian methods of high approximation order in space and time, based on spectral element space discretizations and exponential integrators of Runge-Kutta type. We discuss the extension of these methods to the Navier-Stok

Discontinuous Galerkin (dG) finite‐element methods are well‐known to be suitable for solving convection‐dominated convection diffusion problems. High order Runge‐Kutta methods such as the RKDG and SSP methods have been developed and tested to

Simultaneous impacts of homogeneous and heterogeneous reaction and Joule heating in magnetohydrodynamic (MHD) peristaltic flow of viscous fluid in a symmetric channel are analyzed in this investigation. Attention has been focused on designing and sim
