Unfocused laser ignition of high-pressure He-H2-O2 combustible mixtures

R. Grosso Ferreira, B. Carvalho, J. Rodrigues +4

We report consistent ignition of high-pressure (p > 20-30 bar) hydrogen-oxygen mixtures diluted with helium, using an unfocused Nd:YAG laser. This corresponds to laser irradiances…
