Front tracking applied to Rayleigh-Taylor instability. (English) Zbl 0582.76107

A numerical solution of the two-fluid incompressible Euler equation is used to study the Rayleigh-Taylor instability. The solution is based on the method of front tracking, which has the distinguishing feature of being a predominantly Eulerian method in which sharp interfaces are preserved with zero numerical diffusion. In this paper validation of the method is obtained by comparison with existing numerical solutions based on conformal mapping. An initial study of heterogeneity is presented.
