Abstract

Abstract: The solution of compressible flow on unstructured triangular grids in two dimensions is considered.FEM-FCT for the Euler equations are combined with an adaptive mesh regenera-tion procedure and employed in solution of three examples.Comparisons with experiment data or other computational resuIt show good agreement for the subsonic and supersonic flow around NACA0012 airfoil.However.the location of shock-wave has some differeneehrthe transonic flow.

Key words: compressible flow, inviscid flow, Euler equations of motion, finite element method
