A model of second harmonic generation by Kelvin-Helmholtz (KH) instability is presented. Weakly nonlinear theoretical results of the growth of the second harmonic agree well with the results of the LARED-S code. Nonlinear threshold of the KH instability for the single mode perturbation is determined by two-dimensional simulation.
