Numerical Flow Simulation for a Wing/Fuselage Transport Aircraft Configuration with Deployed High-Lift System

摘要: The flow simulation system MEGAFLOW is applied to the Navier-Stokes investigation of ALVAST wing/fuselage configuration with deployed high-lift system. comparison numerical results experimental data reveals good agreement and satisfying robustness convergence process. Reynolds-number influence estimated by increasing one order magnitude, causing essentially an increase lift on all three components. Within framework wake vortex investigations Euler computations have been conducted. For same angle attack as well for coefficient used in experiments, neglect viscosity yields a deviation from loading single components wing. First evaluations flowfield behind yield plausible results.
