Numerical investigation on the ablative Kelvin-Helmholtz instability

The ablative effect on the Kelvin-Helmholtz instability is attemptly analyzed by numerical simulation. One-dimensional ablative effect is analyzed and some typical profiles are introduced for the two-dimensional simulations. We found that the linear growth rate and frequency are reduced by the ablative effect. The heat conduction stabilize the Kelvin-Helmholtz instability by suppressing the growth and transmission of the perturbation. In the weakly nonlinear regime, the ablative effect suppresses the appearance and growth of the second and third harmonics. Copyright (C) EPLA, 2009
