“…Therefore the disappearance of NGair flame at the net obstacle has no explanation on the basis of the only thermal theory 6 . It means that in the work the direct evidence is obtained that the active centers of combustion of methane and hydrogen, determining flame propagation, have the different chemical nature [15,16]. The reason of close-to-zero velocity value of NG-air flame in the vicinity of net obstacle is due to the fact that light hydrogen atoms easily penetrate through the net obstacle, but chain carriers of methane combustion, on the contrary, are effectively terminated on Al 2 O 3 .…”

It is shown that spark initiated flames of lean hydrogen-air mixtures (8%-15% Н 2) pass through close-meshed aluminum spherical obstacles with the cell size 0.04-0.1 mm 2 ; the flame of 15% Н 2 in air after an obstacle is accelerated; acoustic gas fluctuations occur in the reactor. The flame of 7.5% hydrogen-air mixture does not propagate through the obstacles the flame of 8% natural gas-air mixture is not accelerated after an obstacle; acoustic fluctuations are missing. It is shown that active centers of methane and hydrogen combustion, determining flame propagation, have different chemical nature.

The main objective of this book is to acquaint the reader with the main modern problems of the multisensor data analysis and opportunities of the hyperspectral shooting being carried out in the wide range of wavelengths from ultraviolet to the infrared range, visualization of the fast combustion processes of flame propagation and flame acceleration, the limit phenomena at flame ignition and propagation. The book can be useful to students of the high courses and scientists dealing with problems of optical spectroscopy, vizualisation, digital recognizing images and gaseous combustion. The main goal of this book is to bring to the attention of the reader the main modern problems of multisensory data analysis and the possibilities of hyperspectral imaging, carried out in a broad wave-length range from ultraviolet to infrared by methods of visualizing fast combustion processes, propagation and flames acceleration, and limiting phenomena during ignition and flame propagation. The book can be useful for students of higher courses and experimental scientists dealing with problems of optical spectroscopy, visualization, pattern recognition and gas combustion.
