As the damage due to the explosion accident depends on the flame propagation speed, elucidation of the flame speed for a variety of condition is of importance in terms of "national resilience". Flame instability, which affects flame speed by disturbing flame area, is known to be promoting with increasing pressure. In this study, we investigate the effect of flame instability on flame propagation speed for various types of fuel, by investigating the characteristics of the propagation speed at elevated pressures.
