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 materials’ parameters and operation variables in flame characteristics and stability is elucidated.
