Abstract

Abstract: In this work, the ranges of different combustion modes of a methane-air mixture were studied in dependence on the flow velocity under conditions of a smooth temperature gradient of the channel. To carry out the experiments, a laboratory setup was designed and constructed to obtain a smooth temperature gradient in a quartz tube, and experiments were performed to determine the temperature gradient. The boundaries of different combustion regimes were determined for the mixtures with different fuel-air ratio coefficients (0.8, 1, 1.2), moreover, transient modes between main regimes were found.
