Micro-combustion
Micro-combustion is the sequence of
surface to volume ratio increases heat loss to walls of combustor increases which leads to flame quenching
.
The development of miniaturized products such as
batteries as they have large surface area to volume ratio, due to which, significant amount of heat is transferred through the walls which leads to flame quenching.[4] However, the increased rate of heat transfer through solid walls is advantageous in the case of steam reformers used for hydrogen production.[5]
B. Khandelwal et al. have experimentally studied the
mixtures in a 2.0 mm diameter straight quartz channel with a positive wall temperature gradient along the flow direction.[7] This was a simple one-dimensional configuration to study flame stabilization characteristics in microchannels. Other researchers have studied the flame stabilization behavior and combustion performance in a Swiss roll combustor,[8] micro-gas turbine engines,[9] a micro-thermo-photovoltaic system,[10] a free piston knock engine,[11] a micro-tube combustor,[12] radial channel combustors,[13] and in various other types of micro-combustor.[14][15]
