Abstract: The explicit and implicit methods are employed in the numerical simulation of unsteady transonic NACA10012 airfoil flow,and comparison analyses have been made in the respects of computational results,efficiency,and sensitivity to grid quality.

Key words: unsteady transonic flow, finite volume method (FVM), LU-NND method (TVD)
