Abstract
This paper is concerned with the solution of the steady Euler equation s by an implicit unsteady method of Lax-Wendroff type without artifici al viscosity or upwinding. Stability and efficiency are discussed for various treatments of the implicit operator: direct solution, approxim ate factorization or a few iterations of a line-relaxation method. Com putational tests are presented for a cylinder and an airfoil.
