This paper investigates the use of an Arbitrary Langrangian-Eulerian (ALE) technique on a single-mode Rayleigh-Taylor instability simulation in two dimensions. A finite volume approach on a simply connected quadrilateral grid is used. The effect of various modifications in the ALE method on instability growth, energy balance, and mesh distortion are investigated. It is shown that ALE mesh motion can be used to improve single mode Rayleigh-Taylor Instability simulations. (C) 2001 Elsevier Science B.V. All rights reserved.
