| Abstract: | Both algebraic method and optimal elliptic partial differential equations are used to generate face-patched multiblock grids for F5 wing with control surface deflections.Dynamic grids are generated by the use of a deforming technique.The finite volume method and dual time-stepping approach is used to solve unsteady Euler equations.An effective interpolation method for conservative variables on discontinuous faces is developed for face-patched multiblock grids.The computational results about unsteady transon... |
