Unstable behavior of hydrogen-air lean premixed flames (Effects of unburned-gas temperature, heat loss and scale)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Unstable behavior of hydrogen-air lean premixed flames was studied by numerical calculations of two-dimensional unsteady reactive flow to clarify the effects of unburned-gas temperature, heat loss and scale. We adopted the numerical model containing the
