| Research Abstract |
Flame propagation experiments were performed for a pebble bed at high pressure and high temperature. Flame speed in the bed was measured and OH-PLIF of the propagating flame front was performed. Results showed that the mode of the flame speed changed with increasing pressure and the flame becomes turbulent flame even though it propagates through very small matrix channels. Flame propagation limit was also observed and the limit was proved to be determined by the competition between heat release from the flame and heat loss to the pebbles.
