A New Multigrid Euler Method for Fighter-type Configurations
Transonic and supersonic flows over isolated wings and fighter-type aircraft configurations are computed through the numerical solution of the compressible Euler equations. Appropriate singlemesh topologies are used in combination with a new multigrid time-stepping scheme for solving the Euler equations. C-H or C-0 meshes are used for the isolated wing. A novel H-0 type mesh is introduced to di...
متن کاملAIAA -86-0103 Calculation of Inviscid Transonic Flow over a Complete Aircraft
We present preliminary results for the calculation of inviscid transonic flow over a complete aircraft. These results have been obtained by a novel approach that combines a new procedure for mesh generation with a new finite element method for solving the Euler equations. Introduction A principal goal of computational aerodynamics has been the calculation of transonic flow over a complete aircr...
متن کاملSolution of the Euler Equations for Two Dimensional Transonic Flow by a Multigrid Method
A crucial input to the design of a long range aircraft is the prediction of the aerodynamic flow in cruising flight. In contrast to the flow past a blunt object, such as a golf ball, or ski racer, the flow past an aircraft generally does not separate. Consequently, the important viscous effects are mainly confined to boundary layers over the surface of the aircraft, and useful predictions can b...
متن کاملComputation of Aircraft Flow Fields by a Multigrid Euler Method
An algorithm for computing transonic flow fields about fighter-type aircraft is described in the paper. The compressible Euler equations are solved numerically using a vertex-based, finite volume multigrid scheme. The space around the aircraft is discretized with a single-block H-0 mesh which is generated by the union of separate Omeshes around successive cross sections of the aircraft. The dis...
متن کاملAgglomeration Multigrid and Parallel Processing for the Numerical Solution of the Euler Equations on 2d and 3d Unstructured Grids
Abstract. This paper aims at coupling two known CFD techniques, namely multigrid and parallelization, in an existing Euler equations solver for 2D and 3D unstructured grids. The solver is based on a time-marching formulation for the high-subsonic/transonic flow equations and a pointwise implicit solution algorithm. The gain from the combined use of multigrid and parallelization is the reduction...
