| Abstract: | A finite element model is used to analyze the temperature distribution of metal/explosive di layer materials irradiated by laser. The temperature rise of explosive surface center varying with laser intensity, spot size, and irradiation time is given. The preliminary results about laser ignition on explosive with a metal envelope are got. The subsonic airflow convective heat transfer influence on the target temperature field is also analyzed . |

| Keywords: | laser heating temperature field explosive convective heat transfer |
