microcombustion
Microcombustion refers to combustion processes that occur in structures with dimensions on the order of tens to hundreds of micrometers, such as microchannels, microreactors, and microburners used in MEMS-scale devices. The field aims to provide compact, high-energy-density power sources for portable electronics, sensors, and microelectromechanical systems, as well as propulsion components for small-scale platforms.
At micro scales, heat and mass transfer to surrounding walls become dominant. The large surface-to-volume ratio
Common design approaches include straight or serpentine microchannels, heater-assisted burners, and catalytic microreactors to reduce ignition
Challenges in microcombustion include managing heat losses, preventing flashback, ensuring flame stability over operating ranges, and
Applications span micro-powered devices, MEMS energy sources, and micro propulsion for small-scale platforms, with continued work
