Abstract

The characteristics of combustion in a heated narrow channel with a temperature gradient were studied experimentally, analytically, and computationally. Methane/air or propane/air mixtures of required equivalence ratios and flow rates were supplied to the channel through electric mass flow controllers. Stable flame branches in high and low mixture velocity regions were identified. In the intermediate mixture velocity region, various dynamic behaviors such as repetition of extinction and ignition, and pulsating flames were experimentally observed. Flames with cyclic behaviors and flames with mild heat release, as well as conventional flames, were potential heat sources with various characteristics in future applications in the area of microsystems. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
