Abstract:

A numerical method for solving the three dimensional Euler equations in geometrical complex domains has been developed. The approach divides the computational space into multiple blocks whose structure follows the natural lines of the configuration. A systematic, multiblock grid generation scheme is used to produce the grid. The flow solutions are obtained by solving the Euler equations by a finite volume discretization and a Runge Kutta time stepping scheme. The main advantage of this method is the applicability to complex geometries like for example complete aircraft configurations including wing, fuselage, canard and tail. The coupling with a 3D boundary layer method allows to account for viscous effects. An other application for the method has been the simulation of flows in the presence of a propeller.
