VISUALIZING COMBUSTION USING ELECTRICAL-IMPEDANCE TOMOGRAPHY

The techniques developed for electrical capacitance tomography (ECT) h ave been adapted to characterize combustion phenomena in a scaled mode l of an internal combustion engine. The method is able to locate flame position, measure flame size and monitor the effect of varied air/fue l ratio. Flame failure can be identified. The technique can measure fl ame front arrival time and reliably depict the development of the comb ustion process in a research model of a single cylinder internal combu stion (IC) engine. Low-resolution images at over 300 frames per second have been captured. (C) 1997 Elsevier Science Ltd. All rights reserve d.
