Abstract : The push toward the miniaturization of electromechanical devices and the resulting need for micro-power generation systems with low-weight, long-life devices has led to the recent development of the field of micro-combustion. The concept behind this new field is that since batteries have low specific energy and liquid hydrocarbon fuels have a very high specific energy, a miniaturized power-generating device, even with a relatively inefficient conversion of hydrocarbon fuels to power, would result in increased lifetime and/or reduced weight of an electronic or mechanical system that currently requires batteries for power. The high energy density of hydrocarbon fuels creates a great opportunity to develop combustion based micro-power generation systems to meet increasing demands for portable power devices, micro unmanned aerial vehicles, micro-satellite thrusters, and micro chemical reactors and sensors. In this paper, the recent technological development and progress in fundamental understanding of micro-scale combustion are reviewed. Furthermore, gas-phase combustion in small channels is reviewed. Flame stabilization is contrasted to propagation and the mechanisms for stability loss are discussed. The role of key wall materialsâ€™ parameters and operation variables in flame characteristics and stability is elucidated.
