Abstract

The solution of time-dependent Euler equations for wings using an explicit Runge-Kutta time-marching finite volume procedure by employing a combination of second-and fourth-order dissipation, variable-time step, and enthalpy damping to speed up the convergence to steady state is described. The wing flow fields for an ONERA-M6 wing and an arrow wing are computed utilizing the modular SS-NAL-07 Euler code, which contains a mesh generator and a flow solver. Grid sizes for the wings are solved and presented. It is determined that the Euler code provides good calculations of the flow over the wing; however, more accurate results are possible by increasing the grid cells. (I.F.)
