| Abstract: | A Euler method for solving the flow around a wing-body configuration with deflection of control surface (aileron) is presented. Using the combination of patched grid and domain decomposition techniques, the complex flow around this kind of configuration is effectively solved. An internal coupling condition is given to make the conservation of flux satisfied. In the computation Van Leer-s scheme is used to discretize the inviscid flux terms and a new Limiter function is constructed to realize TVD character. Numerical results show that present method is an effective one for solving the flow around wing-body configuration with control surface deflection . |
