A three-stage Runge-Kutta (RK) scheme with multigrid and an implicit preconditioner has been shown to be an effective solver for the fluid dynamic equations. Using the algebraic turbulence model of Baldwin and Lomax, this scheme has been used to solv

In a joint effort ONERA and DLR have assessed the interference effects of a generic twin-engine transport aircraft configuration equipped with throughflow nacelles. Both experimental and theoretical investigations were performed. The results showed t

The accuracy and efficiency of a cell-vertex upwind scheme are in- vestigated. Upwinding is acheived by an unequal distribution of the transformed flux balances to the vertices of a computational cell. The equations are rotated with respect to the lo

Runge-Kutta/Implicit methods for the solution of the Navier-Stokes equations provide superior convergence rates, especially when combined with a multigrid framework. In previous investigations [7,8,10], the algebraic model of Baldwin and Lomax [1] wa

Today, it is a standard technique to accelerate the convergence of explicit multistage time-stepping schemes to steady state using implicit residual smoothing (IRS) together with multigrid. In the past, various IRS methods have been developed. They a

The convergence of a Runge-Kutta (RK) scheme with multigrid is accelerated by preconditioning with a fully implicit operator. With the extended stability of the Runge-Kutta scheme, CFL numbers as high as 1000 could be used. The implicit preconditione

Accuracy investigations for upwind schemes in the framework of a node based and cell centered discretisation for the Euler and Navier Stokes equation on unstructured hybrid grids are presented. A crucial factor for the accuracy of the upwind discreti

A modification of a central difference cell vertex scheme for high speed flow has been presented. In this scheme the discretization operator for the inviscid fluxes has been changed to a cell centered type operator which is applied to a set of auxili

The computation of inviscid and viscous one- and two-dimensional supersonic and hypersonic flows using explicit Runge-Kutta time-stepping schemes is investigated. The spatial discretization is based on a cell-vertex finite-volume scheme with central
