レーザー駆動デトネーションにおける加熱構造に関する基礎実験

摘要

大スポット径•多ビームレーザー照射によって、平面波に近いレーザー駆動デトネーションを発生させ、その加熱構造を調べた。%Laser-driven detonations were generated in nitrogen gas. In the experiments, self-emission images of the detonations were observed edge-on with a streak camera, and Schlieren images of them were observed edge-on with a gate camera. It was found out that the laser heating of the gas began prior to the shock heating and the longitudinal structure of the laser-driven detonations markedly depended on the initial pressure of the nitrogen gas.
