This paper provides a contribution towards developing robust and accurate multidimensional upwind schemes based on a characteristic decomposition of the Euler equations and a fluctuation splitting space discretization. A new nonlinear matrix scheme is presented which extends the concept of nonlinear advection velocity to the Euler system. The scheme is shown to provide second-order-accurate results for subsonic, transonic and supersonic flows, while capturing shocks monotonically.

Abstract
This paper provides a contribution towards developing robust and accurate multidimensional upwind schemes based on a characteristic decomposition of the Euler equations and a fluctuation splitting space discretization. A new nonlinear matrix scheme is presented which extends the concept of nonlinear advection velocity to the Euler system. The scheme is shown to provide second-order-accurate results for subsonic, transonic and supersonic flows, while capturing shocks monotonically.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
