Unfocused laser ignition of high-pressure He–H2-O2 combustible mixtures
Grosso Ferreira, R.; Carvalho, B.; Rodrigues, José-António; Rodrigues, R.; Smith, A.; Marraffa, L.; Lino da Silva, M.We report consistent ignition of high-pressure (p(fill)>20-30 bar) hydrogen-oxygen mixtures diluted with helium in two different combustion vessels, using an unfocused Nd:YAG laser. This corresponds to laser irradiances several orders of magnitude below the minimum ignition energies reported in the literature. This unusual phenomena has led us to try to measure the amount of laser radiation absorbed by the gas ...
The LisbOn KInetics Boltzmann solver
Tejero-del-Caz, A.; Guerra, V.; Goncalves, D.; Lino da Silva, M.; Marques, L.; Pinhao, N.; Pintassilgo, C. D.; Alves, L. L.The LisbOn KInetics Boltzmann (LoKI-B) is an open-source simulation tool (https://github.com/IST-Lisbon/LoKI) that solves a time and space independent form of the two-term electron Boltzmann equation, for non-magnetised non-equilibrium low-temperature plasmas excited by DC/HF electric fields from different gases or gas mixtures. LoKI-B was developed as a response to the need of having an electron Boltzmann solv...
