In this work different high-order temporal schemes, used to advance in time the DG space discretized equations, are investigated: the Explicit Singly Diagonally Implicit Runge Kutta (ESDIRK), the Modified Extended BDF (MEBDF), the Two Implicit Advanced Step-point (TIAS) and a Rosenbrock method. The proposed schemes are evaluated in terms of accuracy and efficiency for two unsteady test-cases: (i) the convection of an inviscid isentropic vortex and (ii) the laminar flow around a cylinder.

Abstract
In this work different high-order temporal schemes, used to advance in time the DG space discretized equations, are investigated: the Explicit Singly Diagonally Implicit Runge Kutta (ESDIRK), the Modified Extended BDF (MEBDF), the Two Implicit Advanced Step-point (TIAS) and a Rosenbrock method. The proposed schemes are evaluated in terms of accuracy and efficiency for two unsteady test-cases: (i) the convection of an inviscid isentropic vortex and (ii) the laminar flow around a cylinder.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
