A series of ARTI experiments have been performed in Shenguang Ⅱ(SGⅡ) laser facility of China. The simulation results from the LARED-S code for the planar foil trajectory experiment indicate that the energy flux at the hohlraum wall is obviously less than that at the laser entrance hole (LEH). Furthermore, the non-Planckian spectra of X-ray source can affect the dynamics of the foil flight and the perturbation growth. The images of evident growth of the ARTI initiated by a small-amplitude perturbation and the spike-bubble pattern initiated by large-amplitude perturbation were observed. The data of the growth of the second and the third harmonics were also obtained by increasing the spatial resolution in the experiments. The simulation results are in general consistent with the experimental results. The reliability of the LARRED-S code has been tested and validated through the comparison with the experiment results.
