On Numerical Simulation of Flow Problems by Discontinuous Galerkin and Finite Volume Techniques
O. Winter, P. Sváček
Abstract:
The subject of this contribution is the numerical approximation of the flow problems with aid of OpenFOAM’s implementation of finite volume method and in-house implementation of discontinuous Galerkin method in Julia programming language. The advantage of high-order accurate discontinuous Galerkin method is shown on a case with smooth data. Furthermore, the transonic case is computed with both finite volume and discontinuous Galerkin methods and the results are compared.
Keywords:
Euler’s equations, finite volume method, discontinuous Galerkin method, Ringleb’s flow, GAMM channel
