| Research Abstract |
Micro combustors for portable power generation are of great interest for a high energy density with hydrocarbon fuels. In such systems, micro conduits smaller than the quenching distance of flame are usually employed. In the present study, we have examined quantitatively the effects of wall materials and wall temperature on two quenching phenomena ; thermal quenching due to wall heat loss and chemical quenching due to destruction of radicals on the wall. Through developments of micro quarts combustors and a phase-locked OH-PLIF measurement system, we have elucidated the wall effect on flames in micro scale.
