The k-L turbulence model, where k is the
turbulent kinetic energy and L represents the turbulent eddy
scale length, is a two-equation turbulence model that has been proposed to
simulate turbulence induced by Rayleigh-Taylor (RT) and Richtmyer Meshkov
(RM) instabilities, which play an important role in the implosions of
inertial confinement fusion (ICF) capsule targets. There are three free
parameters in the k-L model, and in this paper, I
calibrate them independently by comparing with RT and RM data from the
linear electric motor (LEM) experiments together with classical
Kelvin-Helmoholtz (KH) data. To perform this calibration, I numerically
solved the equations of one-dimensional (1D) Lagrangian hydrodynamics, in
a manner similar to that of contemporary ICF codes, together with the
k-L turbulence model. With the three free parameters
determined, I show that the k-L model is successful in
describing both shear-driven and buoyancy-driven instabilities, capturing
the experimentally observed separation between bubbles and spikes at high
Atwood number for the RT case, as well as the temporal mix width recorded
in RM shock tube experiments.
