| Abstract: | Two dimensional transonic flows are simulated by solving Euler equations with finite volume method numerically.Multi-Unstructured grid technique is used to accelerate the three-stages time marching convergence.Multi-Unstructured grid generation technique and interpolation method are investigated.As an example,2D transonic flows around NACA0012 airfoil are calculated with the present method. |
