Název v původním jazyce

An implicit discontinuous Galerkin scheme for a numerical solution of transonic flow problems

Popis výsledku v původním jazyce

This study is concerned with an implementation of the discontinuous Galerkin finite element method (DGFEM) combined with an appropriate implicit scheme for the numerical solution of transonic flow problems. The DGFEM, which is designed for the spatial discretisation, has the advantage of being conservative and robust and provides an arbitrarily high order of approximation. With regards to the temporal discretisation, explicit method are limited by the CFL condition, which becomes even more restrictive for high orders of DGFEM. For this reason, we instead employ one of the implicit method with a much larger region of stability, even though its implementation is more complicated. The developed implicit DGFEM solver is validated for two test problems, namely a transonic flow in the GAMM channel and around the NACA aerofoil.
