  abstract	= {A numerical study on the benefit of high order methods is
		  performed. Numerical computations of solutions governed by
		  the Euler equations are performed. The propagation of a
		  vortex convected through an empty domain, computations of
		  steady state solutions around a NACA0012 airfoil and
		  vortex-airfoil interaction are considered. These
		  computations show that high order methods are often
		  required in order to capture the significant flow features,
		  especially for transient problems. }
