Abstract

The growth rate of the turbulent mixing zone, which develops from random perturbations under Rayleigh-Taylor instability, has been studied using the 3D version of the hydrodynamical code VULCAN. Previous studies show large differences between the α parameter of different codes. In its Eulerian mode VULCAN/3D employs Van-Leer scheme for the advection of all variables, and can also use interface tracking for multi-phase flows. Simulations using parallel version of VULCAN/3D give α of about 0.06, a value which agrees very well with experiments and some other simulations.
