抄録

A Laser-Supported Detonation (LSD) wave can be categorized as one type of hypersonic reacting flows, where exothermicity is supplied not by chemical reaction but by radiation absorption. To clarify the realizability of steady LSD wave and to analyze the real characteristics of LSD propagation, we have numerically simulated the steady 1-D LSD wave propagating through a room-temperature (300K) argon gas, which absorbs CO₂ gas dynamic laser, using a 2-temperature model. We have demonstrated the possibility of LSD propagating, using a physical model reflecting, as much as we can, what would occur in a real LSD. Calculated results show that a steady-state LSD wave in which incident laser beam is perfectly absorbed is not sustained by the precursor generated by electron diffusion and that the threshold laser intensity to generate a steady-state LSD wave is reduced when cold gas pressure is increased.
